I wonder why...

I wonder why there was an inflatable swimming ring in my bathroom yesterday morning.

I wonder why I later found it in the girls' bathroom...

 I wonder why, hours later, it had migrated to the dining room, even though slightly deflated.

 I wonder why, it finally died on the girls' Dora couch.

I wonder why...I never saw a child actually touching it. 

I wonder why I spend money on toys when apparently my kids are happy to just play with a $3 swimming ring all day.
