Why you should NEVER RESIGN!

ok we should not resign beacause mayebe the other player makes a blundeeer o r or or or ororrorrrrr it could be a draw at theeee end
but sometimes resigning is actually a sign of respect we have towards our opponents.
For me the majority of the time I resign in a losing position (usually because my time is also low and I do not foresee any practical chance of a comeback).
The above is less true, however, as my opponent's rating decreases. I tend to resign less frequently against opponents much lower rated than me.
Or take the following scenario which represents one of the minority occasions where I refused to resign.

You played a tennison gambit???
ICBM?!?!?!
