I have phases; sometimes I go for a couple of months straight, and sometimes I don't go for a couple of months, but I don't go regularly because technically I get bored, it literally loses its point.
I am really not a party person. I grew up in a very conservative home where parties was a no case. I started going to parties a bit in college. For now, the only parties II manage to attend are celebration parties that are hosted by close friends and family.
