If you have a laundry list of excuses just waiting to be used when your friends ask you to go out, you might be a little bit introverted. It’s not that you don’t enjoy your friends, you simply don’t have the energy to speak with all of them, all the time, at once. You’d need at least a month to recover from that. Instead, you opt for Netflix chillage at home on Friday nights. You have short, one-sided chats with your cat, Winston, and you’re happy to crush a box of wine on your own. When hanging by yourself is so awesome, who needs friends? Besides, you were totally planning to Irish-goodbye that party so hard.
