Mad over a pic?

Chatting with a guy on a dating site, we eventually exchange numbers. 15 mins into texting, he sends a pic(it’s not nasty) which I didn’t ask for, then tells me to send one.

I said, no, go on the site and look at my pics if you wanna see any. His response, “hell nah, forget it then”

I mean, why get that pissed because I didn’t send a pic?
