affability / af·​fa·​ble | \ ˈa-fə-bəl  \
being pleasant and at ease in talking to others
characterized by ease and friendliness


Don't get me wrong I'm not an angry or perpetually sad person but its not easy for me to talk to people 

And I'm not that friendly...but I'm not a jerk...just kinda in the middle....neutral...an introverted extrovert...or maybe just a social introvert
