Teachers wise words?

It was last week or something that all the students in our class had a one on one chat with the teacher about their grades. When it was my turn I first got shown my grades and stuff and my teacher asked me how I liked school and so on.

Then he went on to small talk and asked me "you don't drink, right?" and I said that I don't. My teacher said that when he was around 20 like me he didn't drink that much either, but now he wouldn't be able to live without alcohol. "Nai to muri" he said, lol.

"So maybe that will change for you too" he said, and I smiled and said yeaa maybeeee...

So he thinks that I will probably start drinking and then when I am 40+ like him I too will not be able to live without alcohol?

I guess he didn't realized how sad what he said sounds! Who wants to end up like that? Saying something like that just makes me wanna keep away from alcohol even more. Don't wanna end up feeling like I need alcohol to keep going, that just seems like a very sad life.
