4p is What I Got from My Son!

This afternoon, my son came home and ran upstairs.  So I went up too.  Seeing him empty his money box, I thought to myself what is he up too?  Is he saving up to buy toys or maybe Skylanders?About 5 minutes later, he shoved it up to my face with a tiny written note and 4 p:dir mon from kxxxxI no you hav onee alit ul bit of muneSo it is translate:Dear Mom,I know you have only a little bit of money From Kxxxx. 
Behind the note - he written P4.  I think he meant 4p!It is very sweet and thoughtful of him.  But surely I'm worth more than 4 p as he has two £1 coins in his money box!  Well, I suppose it is better than nothing!
