First time poster. My father is 82, in fairly good health (despite a brain aneurysm last year), lives in cosy-sized pensioner housing and looks after himself although does get tired. Every holidays he enjoys hosting a small morning tea for his five grandchildren (3 are my children). He does a bit of fruit and buys some crisps and an apple pie. We are in and out in an hour (in respect of his age and tolerance for smallish children being noisy and childlike). My brother has two children and for some reason asked our Dad to host his one year old's first birthday this year. My Dad asked me to do the cake. I thought it was a bit odd at the time but made the cake and we attended the morning tea party. This weekend just been, we hosted one of my children's birthday parties at our own home. Whilst extended family all there my father asked myself and sis-in-law to come up with a convenient date for next school holiday morning tea. Fair enough and would've done this over the next days. However as my father was leaving this has now changed and I was being asked would myself and three children be free to attend my brother's 4 year old son's birthday party on X date at my 82 year old father's home, just let him know if date worked. Apparently my brother asked him during the day if he could do this for them. Birthday tea going ahead hinged on my agreeing this. My brother has his own house and a wife and is perfectly capable of hosting a party. I have said I feel uncomfortable about agreeing to this. My father has asked me to speak to my brother and has now said he won't host any morning teas for us this holidays which is awkward but I wasn't declining to attend a morning tea, I just think my brother and his wife should be putting on their own children's birthday parties. AIBU? I now have the deep joy of communicating all of this to my brother! Sigh.
