When a conversation takes a turn for the worst

Tonight my mom and I are out grocery shopping and we stop to browse through the carts of reduced items.

There was a cart of health & beauty items, and I came across a box of condoms.

The following conversation progresses:

Me: Want some condoms? They're mint! (pause) Ick!

(I pick up a box of KY warming liquid)

Me: Want some of this? It's warming!

Mom: I've already got some.

Me (horrified): YUCK! Did you HAVE to tell me that?!?!

Mom: You asked.
