My mom is silly

Me: I’m going out with Jem and Andy and Iavana for dinner later.

Mom: We were supposed to go to the Yardhouse with Nannette and Duwayne tonight!

Me: Did you tell me about this before now?

Mom: …….no. :x

Me: WELL THEN. 

xD Why does my family never remember to tell me anything?! It’s funny when my mom does it, cause she doesn’t really get mad about it.
