it is not on - he should have made an effort. so should your children - travel is possible that time of year and although i am a nurse i didn't work xmas/new year, but took the day of my dad's birthday off and we got together to have a quiet, joint mid-xmas dinner. a 50th should be marked, so even finding a restaurant/pub/nice place to eat is de rigeur for that type of birthday. your plan of getting yourself something nice is a good one, but you should also be able to make your feelings known that they let you down. sometimes it feels like you are mum/wife/cook/cleaner etc. for 364 days a year and it smarts when that 1 day which belongs to you passes by without fuss......make it a very nice present!
