I think a pet peeve of mine is when 25-year-olds say they're too old for anything. Let's talk in 25 years when your back hurts for no reason and you have to wear reading glasses to see your phone. Twenty-five is not too old, and while no one at any age should drink irresponsibly, I promise there will be nights where you've had too much to drink. The world will not end because it happened, either.
