Make my life easier – tip number 1 : don’t hide your number

I don’t understand why people call with hidden numbers. I understand that in some occasion this could be useful (I would list head-hunting and consumer services/call centers that don’t take incoming calls, but even for those I have arguments why I think it’s not appropriate), but in most cases, this is totally unproductive.??

From some time now, I don’t pick up the phone anymore when the number is hidden, this makes my life easier :-)
