For some reason, when I turned ten I demanded a surprise birthday party from my parents. To trick me, they ended up planning the party for the day after my birthday. I was extremely disappointed on my birthday, but they sure got me the next day!
ha ha ha thats a good one tho! Your parents tho omg. Thats funny but I am sure it wasnt in the moment. 
It sure upset me at the time, but I appreciate it all the more now!
I know I would have been super upset in the moment.
