I have a daughter who is 17 years old, and English is not our mother language but in our country English is the official language and hence being fluent in English is a sign of good education.
My daughter was a good child (every child is good), she used to listen what we told her to do and was quite cute too. So, when she was 6 years old the year was 2010 and at that time in our country internet was not available in every home and even having a computer was considered a luxury (smartphone didn't even come in my city). The result was that my kiddie had no access to filthy world of internet where one cannot remain free from learning all the nefarious things. Everything was going on fine, she was manner-ful, obedient and soft in nature. Even her friends and school teachers never complained about her rather liked her much.
As I said English education was quite necessary and important but gaining proficiency in it was not a very easy task (especially for kids) and so I decided to have extra English classes when she got 13 years old. With the help of classes and mutual English conversations her English improved more than her friends at school and she started, a kind of, showing her English skill off by talking in English or using English terms even in friendly talks, she was respected for that in friend circle but I was unaware that she was also giving more time on internet than her friends (as the year was 2015 or 2016). I'm sure she watched things which she shouldn't have and learned things that she ought not to. As she was a good student in school, I didn't hear any complaints from teachers about her behavior or something else and things were pretty well till her high school.
When she entered the junior college and a few months passed, I could notice a little change in her behavior I conjectured that she was feeling as if she got a good view of the world and she knew what's the perfect way of life. As junior college is quite demanding, she used to get tired and irritated, she started giving less and less attention to our advices and often cutting us in middle by saying "I know all that". I must admit that she was becoming a little manner-less and consequently unhappy with her relations with her friends.
She is in 12th Grade in this academic year 2020-2021, and as she is from science stream they have to do the practicals. One day, I called one of her friends to my office and started having a little chit-chat with him (it is not unusual for me to talk with her friends because I was always acquainted with her friends and they too never disliked me). After a little talk, I directly asked him if my daughter getting through change for worse, he hesitated and said I could observe it on my own but his expression seemed to say that he had plenty to say but suppressing it for some reasons. I convinced him (or 'cajoled' if you want) to speak the truth, nothing but the truth and he said
Just yesterday when she was doing the practicals and when she didn't get the correct reading she said "mother-f" and became very angry on everybody near her.
I was a little bit shocked, how could that doll like creature speak those words? And then I found many other truths, her instagram posts always contain phrases like "it has been sh*ttiest of all days", "why the f-- I'm not getting my tune?" (she sings very well and plays ukulele). I want to blame internet for her change not her, she is one of the victims of this cultural crisis which happening in my country. I think she thinks curse words will make her quite famous in her peers group, she thinks that cursing in English language rather than in vernaculars will make others to think that she is very good in English. She is getting rude, manner-less, not taking the advices which will help her and disrespecting the elders. How she got out of my hand? She has developed a bad-temper, it's all because, I think, she gave more time to her mobile phone and internet instead of people around her.
