Are you a better or worse person when you're drunk?

Drinking doesn't make me a different person but it does magnify elements of my personality (mostly the good bits, very occasionally the not so good bits).

In terms of helping people, like the car-pushing help, for me it often seems that the thought process I'd apply to figuring out if someone really wanted/needed my help is considerably diminished when I've a few beers in my system. Before I know what I'm doing I'm offering to help or telling someone their outfit is lovely, or other complimentary comments; generally being a much jollier and more vocal version of myself. While sober I'd probably think of these things but by time I've gone through the 'will I? won't I?' process the moment has often passed. While tipsy, quite merry or even proper drunk I rely on instinct more than cognitive reasoning, which I quite like.

Over expressing myself can be a problem, whether I'm saying nice stuff or not so nice stuff, I hate that 'I said too much' feeling the next day. Which is one reason why I prefer nights out that include dancing - if there's good tunes and a place to dance, I'll most likely spend a lot of the night dancing, which cuts down considerably on drunken blatherings.

OP, your story about pushing the car reminded me of an incident at Halloween, a few years ago. We were heading to the early house, after being out for Halloween night and saw two people trying to push their car to get it started. We stopped to help but weren't making much progress when all of a sudden, around the corner strolled The Incredible Hulk. Such perfect timing. The Hulk wasted no time in joining us in our car pushing efforts and before long the car was going, and we waved goodbye to the Hulk and continued on our very merry way.
