Most of the time :~)
Uncontrollably I smile back.
depends on who smiled at me
if it's the person that pissed me off no, but someone else quite possibly
Only after getting really annoyed with them, withdrawing for a discrete period of time, forgiving them, then acknowledging the error of my ways. Of course by then it is highly likely that there will be no-one to smile back at...
no, but you can thank them through gritted teeth :)))
I would say 'what the hell you smiling at?'
I would go for a hug
I can bark politely :)
Yes. An honest smile can turn away all anger. Love is far more powerful than hate.
Most certainly :)
