I just can’t… it might be some counselor’s random cell phone calling me. Plus the kids go to many camps per summer, and many activities during the year, so I’d be constantly updating my phone book even if not for the main issue.

Few years back brother of my spouse took his wife to Spain (thousends kilometrs from here) to drive around and see some sights. At some point they got a flat tire and while he was trying to fix it two nice gentlemans on motorbikes took everything they had by force (including phones). My spouse brother managed to borrow a phone frome some stranger that was driving by. And when he tried to call the only number they both could remember, his fathers, he did not answers.

Can You guess why? Thats right - he also had a policy to not take phone calls from unknown numbers (especially foreign). They had to go to ours country ambassy in Spain (which took a while) and beg for help.

Since that day his father answers all calls :)

The teacher from school or preschool will call from basically random phone. Possibly own phone. Or whatever office she is in phone. Camp counselor always calls from own phone which is fairly often different one then where you are supposed to call.

Neither of these calls often. Maybe once a year you get call like that. But when they call, you really want to pick up.
