An Arse?

I hadn't spoken to the WRS* in weeks. I had sent emails to which he didn't bother to respond, so me, being me, sent him an email and asked what the fuck was up and if being friends with me now was no longer feasible, etc. His response was:

"Don't be an arse."

An arse? Is that what I'm being for asking that my BFF respond to emails? Is that a male thing? Is it the way men think.. if your best friend wants to know why communication has been at a bare minimum, do you guys think that they are being arses?

Just curious.
