On my personal phone, ( I normally don't answer calls from numbers I don't recognize. )
Only just now it rang with a number from the town next to my mother's, and I've got her cell and her um-friend's cell and land line and her doctor's and his partner's numbers all in my phone, but there are many millions of other people in the metro area. How do I know this isn't a complete stranger calling me because I'm high on her list of emergency contacts? How do I know she hasn't wandered off, fallen down, etc. etc. etc.? (I'm aware of the irony in my tendency to let calls that I know are from her go to voice mail at least half the time but pick up immediately when a call could, for all I know, be about her.)
It was an absolutely non-Mom-related organization I've donated to in the past calling to talk to me about their work (and, no doubt, ask if I'd like to donate again). /o\ Quick adrenaline dump and then I hope I was kind when I told the young person I'm glad they're doing well, my donation schedule is what it is, and I have to get back to work. Whew.
