I need a little rant, and I bet I'm not the only one, so I thought I'd just start this thread...
Ds1's very absent parent (lives thousands of miles away and hasn't seen him for 5 years) sent him an email yesterday morning saying "Hi son, send me your mobile number ASAP. I need to speak to you personally. Don't worry, nothing too serious".
And then hasn't got back in touch.
DS1 noticed that 'too', and has been imagining cancer, dead relatives, etc...
I mean, what kind of a self-centred, thoughtless f*#ker sends their child a text like that, and then doesn't bother to follow up? 
DS is 18, and has asked me not to get involved, so I won't... But I'm outraged on his behalf.
