To be annoyed with MIL

[HaveToWearHeels]

Firstly she walks straight in our house if we leave the door open. Even if it is locked she tries the door then rattles it as if is disgust that we have dared to lock it.
Before Christmas PIL made arrangements to come over to see us today at 3pm as they have been away this Christmas (their choice) and they wanted to see DD.
I went out early afternoon and got back around 2.30pm, just got in when MIL walks in, states she is starving and off home to make something to eat as she has been so busy all day. She said hello to DD, asked her what Father Christmas had brought for her and then left, she was here less than 5 minutes.
DH thinks I am being unreasonable to be pissed off that I cut visiting friends short (where DD was having a lovely time with their DD) to rush home to see them. She could have just rung and said they had been held up and come round another time.

Lock your door or else you will be burgled.

We never lock our door when we're in and my family just walk in, in fact anyone who knows us well and isn't worried by our 4 big dogs walks in too. Doesn't bother us at all, saves us getting up for the door.

you don't like her. fair enough. i wouldn't like her either.
keep your doors locked in future.

She is inconsiderate and full of her own importance.I would have been annoyed too. Next time your friend stays as long as you both want and PIL must accept it's your house and your friends, not just them in your life.

We do try to keep the door locked most of the time, especially when we know they are coming. My family would never just walk in, I suppose it is just the different ways we have been brought up but that is another story !

OMG digerd you have hit the nail on the head. Other stories have now sprung to mind where everything has to be about her.
Like on her birthday when she came round for a meal, had been in the house 2 minutes when she let rip at DH because he hadn't rung her in the morning to wish her Happy Birthday, WTF she had been invited round a 3pm for dinner. She the crouched down and said in DD's face "and have you wished me Happy Birthday ?" DD was only three and needed to be prompted, poor little might.
