I like to have cards from close people for my birthday, since I don't often see some of them, but nibble's not a birthday person - we agreed ages ago that for birthdays and Christmas, we'd just do cards, rather than buying gifts neither of us want or need - so we do something else with what we'd have spent (we're going to Brighton before Christmas, this year), and birthdays themselves are pretty low key in our house. We might have some friends round for a meal or a takeaway, but we'd probably do that anyway - it's not a big bells and ribbons event. On my last big birthday, my sister was here and the three of us went over to Calais for lunch - which was different, but it didn't come with balloons :-)
