I'm usually a mixed bag. Like on a day off, I'll plan on staying home and doing nothing all day, so if someone calls me randomly to hang out that day, I probably won't. But one of the only reasons I've always looked forward to school was because it allowed me to be surrounded by people, which never happened as I was growing up since my mom was very strict and over-protective.
But I agree with Kane, sometimes having a social lie requires money and I don't have any so I usually spend most of my time at home.
