Does it make me a bad mom if.....

....I was in the kitchen and I hear these monstrous "elephant" imitations coming from the living room followed by wild laughter?
Does it make me a bad mom if I let it go on for quite a while, not knowing what that obnoxious sound was but hey, they're laughing not fighting?
Does it make me a bad mom if I finally walked into the living room and this is what I saw?

Does it make me a bad mom if the "elephant noise maker" is the hose to my vacuum and they are playing it like a very long tuba....lips right on it?
Does it make me a bad mom if as soon as I took these pictures I turned around and went back to my business in the kitchen?

hey, they're not fighting!
