I'm no electrician, but one thing I have learned, electricity is quiet and peaceful when you leave it alone. But it's sneaky. One minute you're just fixing the socket, and the next minute you're buzzing and shaking and yelling.
A few months ago the triplets were in bed and we were downstairs unwinding when one of 'em started SCREAMING, and we could tell this wasn't the usual "My brothers are being poopy head" screaming either, so we rushed upstairs.
"THE BUTTERFLY BIT ME!!!!!" she kept screaming over and over.
It took us a few minutes to finally figure out, she had a butterfly plug in night light and, probably because we'd told her NOT to, she went over and was playing with it, plugging it and unplugging it.
Got her fingers behind it and yup... the butterfly bit her!
That one is FAR more respectful around electrical outlets now!
