I so hear your frustration with this. I, in particular, get this from my Mum too and most frustrating is that though she always complains if I don't answer and it perhaps goes to voicemail, heaven forbid, I am in a meeting, appointment, or even an interview as of late, but the kicker is .... she NEVER even turns her phone on! Why she has it, I don't know, but yet continually complains when she can't get someone. Hypocrisy, beyond belief. I feel for you. Maybe we should give them each other their numbers and tell them their ours?
