Since you're not that clubbing type, I think you should have a nice dinner with your friends, go back to your place and watch a movie while eating some cake, maybe play some card games after and exchange gifts haha
Either that, or get pissed drunk with your friends

How much money do you spend on average a month? (including car, gas, food, bills, etc.)
