I'm sooooooo bummed

I was working on another post last night....I had a bunch of pictures and a couple videos and all the writing done.....but it kept giving me an error message "cannot connect with host", or something like that. I just shut my laptop and thought I would try again this morning. Well, apparently my computer decided to restart itself and I lost the whole post! GRRRRRRR! I'll try again later if the kids cooperate.
