i feel pity for those who find getting drunk is the way to get themselves happy.
escapism.
a short vacation in your own dream.
a cheap one too.
technically speaking, it does make you happy for a short while. but when you gain your senses, you'd come back to the reality. alcohol is being cruel towards you. it is more cruel than the reality you're trying to run away.

during the day, you're the most ethical and good mannered person.
at night, alcohol turned you into the person you don't even know.
