LayZ boy's children come to visit their grandmother

After I came home today, my mother told me that my brother LayZ boy's children were coming over today after the older one finished work. She said that they were coming to see her and everyone. Sure. It's most likely their mother told them they should visit their grandmother, because the older one's 21st birthday is coming up soon and she wants to make sure their grandparents buy her something nice. LayZ boy's ex-wife is just as bad as him.

I told my mother that it wouldn't be a good idea for her to have to girls in the family room because they wear really strong perfumes, deodorants and body spray and the family room would reek of it all night. Sometimes the smell is there for days. My mother, of course contradicts me, tells me that she can have them in the sun room, because it's cold. I told her that she had a heater and as its a sun room, its a lot warmer than the inside of the house. She of course told me to shut up, that she wasn't going to do what I suggested.

The thing is, their strong perfume makes me ill - I get so allergic just being subjected to it for even a moment - and none of them care about this. To my mother, its more important to do the complete opposite of anything I ask for (nothing ever unreasonable), wilfully disregarding my health!

When the girls came, she had them in the family room, sitting on the  breakfast stools, but only for a short while.  Even she realised how strong their perfume was and how much it was bothering even her and that she wouldn't be able to handle it when they left and the aroma pervaded the room for hours afterwards.

So only after the girls had been there for about 5 minutes, she ushered them into the sun room.

It is just irritating that my mother just does not listen to anything I say even though I am invariably right in my suggestion or reasonable in what I have asked for. My mother always argues with me, tells me I am wrong, tells me she wont do anything to help me, that she considers her guests needs before mine (they have no needs, it's me that has the severe allergies) and is just wilfully antagonistic towards me.  But invariably, she realises she is wrong (but she wont ever admit it to me) and does exactly what I recommended in the first place.

It is so utterly galling that my mother argues with me so vehemently, tells me I am so wrong, then she does exactly what I suggested because it affects her. She doesn't care about me, she doesn't care that it affects me, she only cares that it affects her. My mother realised that she would have to open all the doors and windows and that still wouldn't get rid of the smell, that when she does that in the sun room, it takes hours for the smell to dissipate and because it is cold tonight, she couldn't bear to keep all the doors and windows open as that would make the house cold, but she could leave the windows open in the sun room and that wouldn't be a problem. So basically, because it was going to affect her, she movies the girls to the sun room and not because of any concern about my health. My mother, like the rest of my immediately family, is so completely selfish!
