Thanks all. :-)
I think that's it isn't it, you don't expect gifts but you do expect an acknowledgement of a HB after all you do for them throughout the year, I would have been quite happy with that.
For those of you who have asked why my husband didn't remind them, I know. He seems to think that they are just children and he just sighs, rolls his eyes and says 'that's teenagers for you' or 'that's boys for you'. I don't get it and find it incredibly frustrating but I'm not about to fall out with my husband over it by having a go.... again! haha.
They didn't actually bother to do anything for him for Fathers Day, even though they were here and I text them to say 'have you forgotten it's fathers day? I'm going to go to Waitrose now and you can come with to get your Dad something'. The message was read and no acknowledgement ever made.
Neither of them have ever been taught about the feelings of others and how important it is to mark occasions. They don't do anything off their own bat.
I've also been the main person sorting finances and accommodation outings for my older SS's university and am really wondering why I bothered.
I'm definitely stepping back now. My older SS has a driving test today (his second) and usually I'd send him a 'good luck' text and I've deliberately not.
As my Dad would say 'Tittle to them'.
