The "non-alcoholic" (for Weezer)

So I was chatting with Weezer yesterday (my nearest & dearest pal)...and we both have a question about folks who claim they like to drink alcohol but never actually have a drink - at least not in front of us.  Why is it that people don't want to have a glass of wine, a beer or any sort of cocktail but won't say why they don't want to drink?  When they are offered a drink, they always give the same response:  "oh, give me a few minutes and I'll join you."  OR "I'll have wine at dinner."  But then they never do...  Honestly, if you happen to be a recovering alcoholic and can't have a drink - then that is totally fine.  But don't LIE about it and say that you are a "big drinker" then never have a drink.  It only makes us more curious and then talk about it later (like I am doing now in this blog).  It also makes us feel bad because perhaps we're offering or pushing to someone who seriously has a problem.  It's totally ok to be a recovering drunk and not be able to drink.  It only makes everyone uncomfortable when you claim to like drinking but then never drink.  Be honest, tell us the truth about your drinking issues.  If you're a recovering alcoholic or a drunk or something - we want to know so we can respect your needs.
