This happened some years ago....
My Friend: Happy New Year!!
I: Idiot! Have you gone nuts?! Where the heck did happy new year come-in in the middle of the year!
My Friend: Its 1st Muharram.
I wish I had a camera and I could take my picture. I swear it must have been a picture of the most idiotic of creatures on the planet. So much for my muslim credentials!
p.s: Happy New Year!
