be mad for a reason

I got a dirty look for the Wally World (Walmart) cashier for laughing @ my 8y/o when he farted.

It was loud and it stank.... Instant funny in my book.

I guess she gave me the stink eye because I was laughing at my child... Actually I was guffawing while pointing but whatev...

I didn't get upset though...

You can be mad at me for laughing at my kids but you should really be mad at the fact that I teach them to laugh at you and your kids. HA!
