Interesting post Panda! I am of course no expert but out of own experience I can say certainly yes! I see many sides of myself in the way you describe yourself. When I meet people for the first time I am outgoing, smiley and not shy the bit. No problem for me to interact with new people that dont know me beforehand. But when it comes to work and social gathering where you actually try to get friends I am the complete opposite, introverted, not talkative and avoid people as much as possible. Because of this I have no friends and no network. Regarding yourself Panda, what do you do between classes? I imagine being a teacher there is a lot of socialising between classes at the lunchroom, drinking coffee etc...do you participate on this?
