I'm like most people so far. I like smoking with people sometimes, but a lot of the time it's nice to just smoke when I feel like it by myself.
Small groups, 4 or less, are way better than big groups of people all trying to share the same bong or joint. If there's more than 4 or 5 people, then I prefer to have multiple joints/bongs/pipes/whatever going around or I get antsy. I'm just like "come on, i want to smoke already". Especially when it's completely my stash or mostly mine and I'm trying to be nice and share, haha.
Might not be socially accepted, but I love lighting up a nice skinny J for a long drive. I used to make a 3 hour drive on a regular basis and it was perfect for a nice single-person J to just cruise and think about things while I'm drivin down the road. So that's a time I def prefer to smoke alone.
