I'm going to kiss my friend on the cheek while drunk
Is your friend going to be okay with drunk gesture?
It's an offer which I can't refuse
Maybe your friend doesn't want to be kissed and if you plan to use being drunk as an excuse, you might be due for a bad awakening. You should respect other people's boundaries and not force yourself on others. It might ruin the friendship.
I think you're overreacting, everyone loves cheek kisses.
Not everyone. Take me for instance. I don't like drunk people doing stupid stuff just because they are drunk they think they can get away with it.
