Your ability to deduce sarcasm could use some work. Heartfelt apologies to all who took offence. I thought it would have been taken as an obvious joke to the lady I responded to.
Lastly people saying such things and being serious is pretty common on this site.
If it were only My inability to catch your sarcasm, due to my own lack of understanding, what is the purpose of apologizing to others? And where is the personal criticizim to them for not catching it?
