Mary left me a note

So it's around 11am and Mary is making her semi-weekly unannounced visit. At least it's not 8am or some ungodly early time, but I want to condition her to call me first, or I'm not gonna open the door. My car was in the driveway, so she knew I was home, but I didn't answer the door on purpose.

So, as usual, she leaves a note. It said:

I'm at Stella's (her sister's crib around the corner). 546-8989. Call me, I need to see you.

Mary.

Well, it was Sunday, so I had my religious meeting to attend and afterward I was invited to a dinner gathering, so I didn't call. I got home at around 8:30p and she had left another note. This one was a doozy...

Vince,

It's 5:00 and I've been waiting at Stella's for your call.

Thanks for nothing,

Mary
