Me: Hi, did you call me about an hour ago?
Mom: No... I wouldn't call you during class, why?
Me: Well I got a call from a Restricted number, which means it was probably either you or Stanford.
Mom: I definitely didn't call you.
Me: Interesting, I guess that means--
Mom: Wait, is this ______?
Mom: Yeah, I did call you. I wanted to talk about your flight home for spring break.
Me: Let's talk later.
I thought that only my mom confused her children. My sister and I are 10 years apart, too, so there's really no excuse.
