It happened again, only weirder

Brad is on call this weekend. I got to talk to him a little this morning and he mentioned a big surgical case coming up this afternoon. I wished him luck and told him I would talk to him later. I am pretty tired after a lack of sleep last night, so I was on the couch taking a nap while my SugarPea was taking her nap.

I was roused from my nap by the phone ringing.

"Hello?"
"Hi, did you call Brad's phone?" (male voice this time)
"Uh, what?" (I'm still groggy and trying to figure out if he meant 'is this Brad's phone' or what was going on since I know I didn't call Brad)
"Are you trying to reach Brad?" (light bulb comes on in my head)
"Oh! My kids must have tried to call him. Is he in surgery?"
"Yes, he is all scrubbed in."
"I'm sorry for the trouble."
"No problem."

I then told the boys this wasn't a good time to be calling daddy. Obviously, I can't fault them for wanting to talk to him. They didn't know he had surgery this afternoon. Oh, the joys.
