OP your comments are a bit condescending don't you think? I do... and insulting.
Apparently you find our help childish?
I too have my actual mug posted here, though I am a kid at heart, so what.
I too cut-my-excel-teeth here on this board.
I have always gained 10 fold of any help I've given. I've been given so much why would I not give back?
We all learn from teaching, so in that respect I am selfish by giving. You apparently are selfish by not giving.
If you are not learning by teaching, then I'm afraid your arrogance impedes you.
The mere fact you feel it necessary to question others' kindness and selfless acts calls into question your personality.
I wonder if you conduct yourself in this manner in real life, person to person.
My guess is you are a cowardly keyboard Rambo.
Have a good day sir.
I hope you find some peace for your heart that you are drastically in need of.
