Pinterest - my love/hate relationship!

I am a newbie to Pinterest! I thought I wouldn't like it.  It sounded stupid...blah blah blah.  I finally decided to check it out. It's actually pretty addicting. Which is great because I needed another way to ignore and neglect my kids for long periods of time, Facebook just wasn't doing it anymore.   I am in love with it.  So many good ideas that I just wanna try out, like right now well the kids are still up running around screaming but , really whats the worst that can happen.  For starters yesterday I saw a couple things that needed a glue gun, long story short I burned my finger.  Today, I wanted to do a little project on Harmony's wall.  Now I am not a complete idiot, I had a back up plan.  I would just use the spare paint in the garage to paint over it, if it didn't turn out.  I didn't like it.  It was too dark.  I could have made it look nice and work but I changed my mind.  I started scrubbing it off enough so I could re paint the light yellow.  I grabbed the spare paint, opened it up, dipped in my brush and one second before I went to paint it on the wall I noticed that it was the yellow for the kitchen not Harmony's room.  Crap, I checked every left over paint can and not one matched hers.   *&%#% Now What??  I start scrubbing harder and most of its off but not it looks horrible.  I then had a stroke of genius.  Thank God for Magic Erasers. It completely took it off.  The yellow looks a little worn, but I will put up a picture or something.  Our House Warming is on Sunday and since the yellow was painted by the previous owners there was a slim to none chance of matching the paint, and I would have had to find a giant picture or cancel the party.   I have now learned my lesson.  Don't paint on the walls.  Its a bad idea! I now hate pinterest.  I am tired and grumpy and have no interest in pinning anything...well at least not for a few hours anyway.
