Like a four, I don't like doing things on my own such as social situations, I'm only comfortable in gatherings if I know someone there, then I stick to them until I start to feel more comfortable around the other people. I can do other stuff by myself though, shopping, errands, movies, food. I'm pretty comfortable being by myself. My little sister is completely the opposite, she's outgoing, will talk/argue with anyone and get's very lonely if she's by herself.
