A few posters on my other thread encouraged me to post here, I hope that's okay as I didn't even know this board was here before now 
I do feel bad posting this as I feel it's disrespectful to my family but here goes...
My DB (26) seems to be the golden boy who can do almost no wrong. My parents do seem to favor him (but don't realise they do as when I point things out they look baffled.)
Some examples:
-growing up, he was always allowed to sit in the front seat (and I always had to have the back seat. There was no turn taking, I was just always sent to the back seat so he could have the front one. When i tried to argue my point I was told off.)
-once I learnt to drive, I was expected to drive him/pick him up whenever he required (still happens to this day if family are together)
-if we are all together at family gatherings (they are all here for Christmas) asking him to do anything is met with refusal and shouting. I don't think it's much to ask him to empty a bin/help with dishwashing duties while he's here over Christmas but apparently I am being massively unreasonable as he is here to relax 
-He doesn't drive, so mum will collect him at all hours of the day and night, even if it's a massive inconvenience to her - she lives about 20 mins in the opposite direction to him and then a further 10mins more in his direction to his workplace (including early hours after a party etc) as he doesn't like to pay taxis and never offers to pay petrol
-He works full time and rents his own flat, but they're always buying him food and his shopping as 'he doesn't have much money.' (They cannot really afford to do this)
-when we all met up the other week at their house, they kindly bought us all a takeaway. Brother ate his meal and was still hungry so mum offered him her meal and said she could just have toast (even though she had paid for it and would mean she would be going without any food.)
-I am expected to run around after him like some sort of Prince too and whenever I put my foot down, I get told I am unreasonable. There are lots of other examples of things but it seems silly to list them all.
When I write it down, none of it sounds that unreasonable and I will probably ask for this thread to be deleted as it makes me sound like a horrible person.
