Wow. I didn't know about the ambivert thing. I googled it and yeah... that pretty much nails it.
Sometimes I'm way too loud and won't stop talking... on the other hand I really need to be all by myself every now and then. Some time.. not too much or I will get in a bad mood too XD I love talking to people..but I hate smalltalk... so so so much. Why would people talk about things they are not interested in?
But keac, why would you say you're an ambivert? Of course it's always a point of view and it's not like there is one drawer for each word, but what you mentioned sounds more introvert. It's not like introverts don't have friends, decide not to have friends or don't like people around them in general.^^
