Memories

I was laying here trying to fall asleep, thinking about life.. I was thinking about when I was little, and the family used to all go swimming, or all go to wet'n'wild. We'd bring food and have a sort of picnic. We both had pool floats, his was a tube-like shark one, and mine was a flat lobster.
My brother and mother and I used to play this game with little blocks. The blocks had letters on all sides, and you'd shake them up in this little container. They'd fall down in a random order and you had to try to find words in the letters.. We had so much fun, I remember my brother and I used to try to make up words and pass them off. We'd laugh and giggle..
They're both dead now, and I'm the only one left who remembers. All those times, all those good times, it's almost like it never happened... What proof is there that it did? My memory? I can't trust that, my memory..
