I had several, since I was either moving or they were moving. I never lucked out with many permanent friendships. Might be why I get paranoid about friendships breaking so easily.
But the first one I can remember was Heather. We were buddies. She lived 2 houses away. Sometimes I would go over and make shrinky dinks in her oven or we'd dance to Thriller. Those were good times :)
Don't know where she is now. I hope she's doing well.
