good bubbles and bad bubbles

Did you know that there are good bubbles and there are bad bubbles? I did not. But now I know that some bubbles are happy and fun and some are just plain old scary. Here's how I found out... The Little Bee got a bubble machine from her Aunt and Uncle and cousins for her birthday. Lately we are not allowed to go outside with out the bubble machine turned on. By not allowed I mean there are lots of shreaks of protest and lately a very emphatic yell of "Buh! Buh!" that come out of my little angel's mouth. Even when she is not playing with the bubbles, she can hear me turn it off and comes running and hollering. So those are the good bubbles.
On to the bad bubbles. Little Bee likes to play around the bathtub while I am getting ready for work, and on this particular day, she tossed the baby shampoo into the tub with considerable force. I didn't know that the top had opened and half of the soap had spilled out until I turned on the bathtub and returned two minutes later to an I Love Lucy sized mound of bubbles. "No use crying over spilled soap" I thought to myself and plunked the little one down in the middle of it all. Bad bubbles! Bad Bubbles! We even scooped out 90% of the bubbles and she still looked at the tub like it was going to eat her. Now I know. Bubble machine bubbles good, bathtub bubbles bad...
