Regarding:
I wore red with blue today!!!!
or
Should I keep or return?!!!

Overly frequent use of the exclamation mark is generally considered poor writing, for it distracts the reader and devalues the mark's significance.
Cut out all those exclamation points. An exclamation point is like laughing at your own jokes.
—F. Scott Fitzgerald

Yes, I know this is piddly, but it does irk me so. Not everything is exclamatory in this world.

Things like:
I got the job!!
or
My two year search is over!
or
The cancer is gone!

are totally exclamation worthy.
