Same here, I don't want any of it coming back
So...what have we got so far:
GOOD
Holding doors open
Being yourself
Being polite
Be casual
offering, but not insisting, help
not being an addict*
*Soda is ok, cafeine is marginal
BAD
Being rude
NOT holding doors open (open to debate

)
pick up lines of almost any sort
being macho
being sterotypical
wearing sunglasses in doors
Anything I missed?
