Only if you and gr8mom exclude her from the fun...
The person below me has a spouse who never plugs in her (or his, I suppose) cell phone and so is nearly impossible to reach particularly since she (or he, I suppose) never checks the voicemail either.
Not necessary for a "true," but extra credit if you were planning to have dinner with another couple tonight but now you aren't because when they called to check if you were still on the phone was not charged despite your SO having been reminded to plug it in, and once the phone was discovered dead and plugged in she STILL didn't check the messages until after the guests were supposed to have already arrived, only then to find the "are we still on for dinner tonight?" message. Still extra credit if the dinner was already mostly prepared.
