My friend Peter Bay’s birthday is on the 29th of February (leap year) so he only has a real birthday every four years!! So he decided his birthday party was only to be every four years. It was Peter’s birthday in 1 day but his mum didn’t realise it had been four years so she didn’t throw Peter a party! The next day Peter walked into the dining room thinking it was his surprise birthday and he walks in and says…
“Thank you all for coming tod…” just as Peter was about today today he realised nobody was there and He then said to his mum…
“I thought it was going to be my surprise birthday party today!”
His mum replied “OH DEAR, I FORGOT IT WAS LEAP YEAR!!”
