I have recently become aware of a disturbing pattern of alcohol consumption by my father. I am 16 and in the past few years I have noticed that my father has started (or at least I have started noticing) that he stores 2-3 beer bottles in the refrigerator every evening and later I can hear him opening them and can smell the alcohol in his breath. I don't have many other close interactions with other people so I don't have a sense of what is considered too much but it seems to me as if that is a very large quantity to be drinking every day. To add on top of this, he doesn't know that anyone knows that he drinks at all. An Example: He will go to the store, hide the beer in the trunk and sneak it into the house after everyone else has gone to bed and then every night sneak to/from the refrigerator with bottles in his pockets when he thinks that we aren't looking. As far as I know, my mother does not know that he drinks at all and I have seen him look startled a few times when he was sneaking around which made it appear that he was hiding it from me too.
Is this normal or is this something I should be aware of and potentially try to recommend counseling of some type?
