nothing, it was a great b-day from the people that were home. Half the family though was elsewhere we never had a sit down together. We've done this before, 2 years ago we celebrated christmas in late january because of conflicting schedules. Its nothing about love its just my birthday has been postponed. Its rather odd. Since the postponedment my mom and sis haven't done anything or said anything about 'happy birthday'. etc.
Equivalent would be delaying a wedding on the wedding day, then when you have the wedding its sort of moot and nobody shows up because they couldn't make it.
