MIL is currently in a huff with us and hung up on DH earlier. The story is...
We eat dinner between 5:30 and 6ish. The time between 5:15 and 6:15 is general chaos in our house. MIL knows this. She has been at our house frequently at this time of the evening. The reason I know she knows is that the three times this week that she has called (at exactly 5:30) she has started the call with "I know you are trying to get dinner on the table and it must be chaos but..." and launches into a detailed explanation of why she rang, as I balance pots, stir things, and generally try to keep control of two hungry grouchy children.
So when she did it tonight just as I had nearly upended a full pot of bolognese sauce all over me, had DD2 clinging to my leg and was generally fighting a losing battle against the chaos, I cheerily said "oh yes, in fact I think I'm burning it, I'll just pass you over to DH".
DH was trying to finish up some urgent work in his office (had I known I would have just told MIL we'd call back), so when I passed the phone over he said he couldn't really talk, asked was it urgent and if not could he give a call back after dinner.
At which point MIL huffed "oh never mind", and hung up on DH. And is now apparently not talking to us. (that last part is DH's interpretation).
AWBU to think she shouldn't ring at a time that she knows is totally unsuitable (and it's not like she can't get us at any other stage of the evening. We don't go out at all
