It was my son's birthday recently and top of his list was a Nintendo switch. I told him from the start I wouldn't get it as he has another older console that was given to him by a relative after he bought a new one which I felt was sufficient.
Anyway he asked his GM who said she would buy him the switch. I warned her at the time it was really expensive but she said no it's for my first grandson etc. I didn't give it much thought and didn't encourage ds telling him she might or might not get it dont get too excited.
My ds started boasting to his cousin who is also games console mad that he was getting a switch which I heard and kept reminding him not to get his hopes up. My nephew has loads of techy things e.g. ipad, games consoles etc but kept going on to his mum to get him a switch and after a few weeks of this she did. Now her son began boasting to my ds that he got a switch before him. 
My son then really became fixated on getting his switch and couldnt be distracted. It also didnt help that he had played on his cousins and his cousin had at times made him feel bad because he hasn't got one. To console him at those times I stupidly said oh remember grandma said she would get it but in my defence she had to both me and him.
So come the day of his birthday he of course was eagerly waiting for grandmas present only to find that she had got him a toy instead because the nintendo switch was too advanced for his age (he is under 10 think key stage 1). You can imagine how disappointed he was.
Now I am put in the position of having to get him a switch partly because gm let him down and partly to keep up with the bloody Joneses cause my sister just couldn't handle her ds going on about it so bought it to get him quiet.
AIBU to be annoyed at both dsis and ds's gm?
