They were playing a sport called bathgame. Wrong!
Damn aphasia, or speech loss.
I was pretty sure the sport ended with ball. bathball? No.
Probably it began with a b. I started running through the vowels: be, no, bi, no, definitely not u, maybe y? Wait.... bay? that's it...
They were playing baseball!
That's aphasia for you: sometimes your words come to you 3 minutes later.
