If you take two boys outside after nap time, their going to want to have a snack at their picnic table.
While they're eating, they'll see their toys and decide it's time to play. When they're playing, they'll run around and pull each other in the wagon.
It won't take long until one of them sees the big puffy clouds in the sky, which reminds them of bubbles, so they'll ask for their bubble guns.
They'll start by blowing bubbles in the wind, but it won't take long before "little boy mischief" sets in
and they start blowing them at each other.
Then a little sister will start to cry and it will be time to start dinner, so mommy will go inside and stand in the kitchen where she can keep an eye on the two little mischief makers. However, it won't be long before two things happen, blowing bubbles gets boring and the bubble bowl spills. So being the best little mischief makers around, they will decide it would be WAY more fun to make bubbles on EACH other while mommy is busy over a saute pan.
This will lead to hysterical giggling, which you can't help but join in.
And after you've sprayed them off with the hose and taken them inside,
they'll probably ask to go back outside. : )
