Years ago when I was living with my parents, my mother was at work, I worked nights. She called me during the day and this was the conversation :

Mom: I need a favor, go into my bedroom, get my cell phone and bring it to me.

Me : you are are work right?

Mom: yeah

Me: you can’t make personal calls at work so you must be on break right?

Mom: what? Just bring me my phone!

Me: if you are on break, how are you calling me?

Mom: oh shit, nevermind I found it.
