People love and feel comfy with stereotypes. Pick one. Eccentric teenager? Benevolent uncle? Be the best you can be within your own stereotype.
I am NOT saying you are your stereotype...I am saying you are a stereotype and then much more...but ppl love a stereotype.....why should you do this? It works is why...and makes you appear to be less of a confused person. It's not easy to find a correct stereotype...and really work it. And then life changes and you might be handed another one. Best social rule ever? Learn the affectations that make you fit into your stereotype. If you disagree...you simply do not understand.
