DSD is 14 and is at ours tonight because she was supposed to have a drama rehearsal which is nearby ours. We live near her school and drama club, whereas her mum lives nearly an hour's busride away.
The drama rehearsal has been cancelled because of snow. DSD's mum has presumably had an email telling her this (as will DH have had too I think, but he's still at work) So DSD's mum tries to phone DSD but her phone is out of charge, so she gets DSS to ring me on our landline to tell me. DSS sounds stressed and says "we've been trying for ages to get hold of DSD" - this is bloody stupid. His mum knows that I'm the one who's at home and is feeding DSD prior to the rehearsal, she knows I'm the one who needs to know that it's not on. She has our landline - obviously. Yet she needs to get DSS to ring me, as she can't just speak to me on the phone 
This has really pissed me off. There are many, many times when the DSC stop by here at the moment because it's convenient for them - I'm happy to have them here and it's not usually much bother feeding a couple of extras (I have my own DC too) but why can't she just acknowledge that I'm doing that?
