That is so cool treasure those memories. He sounds like a neat kid.
One of my favorite things Anthony did was save money he earned for quite awhile and when my step-mom and Dad came to visit us in Boston, he treated them to dinner at T-Bones his favorite resteraunt he orchastrated the entire thing and the waiter goofed at the end and came to us with the bill. Anthony looks us (he was 5) and says I'm PAYING he had a little blue plastic box that he had all the money in (I still have it) he also tipped hugely LOL
So cherish these times. they are so great
