NWMâ?¦this is an awesome threadâ?¦.

You should be a communication majorâ?¦.

My professors would trip on thisâ?¦.



Anyway Iâ??ve found that if I know the person â?¦..I give the up nod (like hey whatâ??s up)â?¦.and if I donâ??t know the person I give them the down head nod (like an acknowledgement or gesture of respect)â?¦.



This is something I will definitely put more thought intoâ?¦..
