<human>: I'm typing this on my phone in the bathroom because I don't want anyone seeing it. This just happened.

My coworker/friend who sits near me at work was on the phone sweet talking his girlfriend. I overhear him saying "How much is it going to be baby, I'll pay for it.---because I want to---no babe it's fine, don't worry about a thing it's completely okay"

We have a dark sense of humor around the office and I jokingly said "Aw, that's so sweet you're paying for your girlfriend's abortion" and he put his hand over the phone and looked at me with wide eyes and fear and whispers "How the fuck did you know? You could hear our conversation?"

I profusely apologized and said I was joking and explained the whole thing but it felt more like digging a whole and trying to back out of a mean insult. I'm in the bathroom and I don't want to leave.

Can you provide a brief overview of the text?
<bot>: Overheard my coworker saying he'd pay for something over the phone, jokingly said he's paying for an abortion. He is.
