Alcohol is a curious little substance as people's personalities tend to change a bit when under the influence. We all have those quiet, tough-guy friends who become garrulous puppy dogs when they're drunk, and then those other friends who are absolute nice guys during the day but once the sun goes down and the liquor flows, they become angry monsters.
Then you've got people like me who just become more insufferable versions of themselves.
There's no denying though that the difference between someone drunk and sober is pretty friggin' significant. And sometimes our drunk versions of ourselves try their best to help our sober selves out. And other times, well, they're total d**ks.
