Last weekend, DP took DSS to a local spring fayre type event - while there, DSS entered a competition to win some electronic gadget or another.
DSS has just spoken to his mum on the phone, and apparently, he won the prize
- it arrived at his mums house this morning; she has opened it and told him all about it.
I'm peeved on a number of levels -
Firstly - WTF is DSS mum doing opening DSS post when he's not there? I'm sure that she would breathe and take a pee for him if she could - he is not allowed to do anything independently 
Never mind the fact that DSS now want to go back to his mums as soon as he can to play with his new gadget - it's taken the shine off the treat that DP had planned for tomorrow 
I also feel, probably selfishly, that DP should have got the enjoyment of seeing DSS open the prize; his mum has taken that away from not only DSS but DP as well
- but DP has only got himself to blame, for that really 
Probably most importantly, am I unreasonable to think that DP could/should have encouraged DSS to put our address on the form? We have worked really, really hard to reinforce to DSS that this is his home too - ensuring that we do not refer to DSS time here as "visits", ensuring he has a say and responsibilities even though he only spends a few days a week here etc. I feel as though I have been putting a lot of effort in for nothing 
I'm p*ssed off with DP and DSS mum at the moment - not sure who I'm more cross with though
