My family has 3 birthdays in the space of 4 days - Son's, daughter's and OH's. The real problem has been buying birthday cards. Come September or October at the latest, all the shops seem to clear away the birthday cards to make way for rows and rows of Christmas cards. What few birthday cards that remain are rarely to our taste and there seems to be a card for every possible relation. Happy birthday second cousin three times removed.
I'll have to start buying their cards in the summer.
