Just before Christmas dh spent quite alot of time fixing my parents computer and saved them alot of money (my mums computer actually). My dad asked me how much he wanted for fixing it and knowing dh he wouldn't have wanted any money so I said I don't think he'll want paying, to which my dad said "oh no we will sort something out", so I left it at that.
When they came round just before Christmas my dad thanked dh and again said "he'd sort something out", however there have been no thanks from my mum, which is very unlike her. She probably thinks she has thanked him but forgotten iykwim.
Last year I noticed mum and dads fridge had alcohol in which I thought strange as they don't drink. It was bought for my sisters husband for putting some music onto my dads mp3 player. I have no problem with this however I feel a bit awful for dh as he spent such a long time sorting the computer out. Dh hasn't said anything btw.
It it unreasonable to be a little bit annoyed by this. I'm not really sure whether to bring it up or leave it alone as its about 5 weeks since he fixed it and I wouldn't really know what to say.
