Kindle Issues

My Kindle is acting strangely. Yesterday it shut down and It wasn't coming back. I called Amazon and we tried several things but they finally said it was dead and I was ready to get a new one. This morning I got up and decided to see if anything had happened. It came on right away and so far is fine. We'll see what the rest of the day brings. Beautiful spring weather here today. I'll be cutting back my rose bush and doing a bit of yard work...later
