Guys and Girls

This one's for Summy. I couldn't resist posting this, though I'm not supposed to write about her.

She was learning genders for animals in Hindi. "Haathi, Haathini, Sher, Sherni, Bile, Gaay". She stopped and stared at the words "Bile" (bull) and "Gaay" (cow). And then she said:

"Daddy, if a cow is a girl, why do they call it a "guy"?"
