Memoria

What makes a memory? Does it have to be fun? What about the un-pleasant ones? Which ones stand out more? Why? What makes them more important than the others? What makes a memory different than something you remember to do (ex: fun in the park vs. learning addition)? I don't know what it is, but memories have been my "thing" over the past few days. The ones I have, Big Man has, the ones Little Man is currently making. I worry about what we leave behind. For us, for Little Man.
