Sometimes moms forget to buckle their little boys into their strollers. The reason for this might sometimes be that the mom knows in the back of her mind that the child won't try to climb out and is too old to slip out. However, because the mother might normally buckle the child in anyway, it might also be partly due to forgetfulness.
In cases when this happens (or rather doesn't happen--the buckling, I mean), there are few surprises less welcome than, when the child has been peacefully sleeping in said stroller for some time, the stroller suddenly begins to slow, there are dragging sounds and then, unexpectedly, the sandal of the sleeping child appears near the mother's feet, coming out from under the back of the stroller. And however much the mother might hope he isn't, the child might still actually be wearing that sandal.
Yes, sometimes mothers run over their own children with their strollers, and the little ones sometimes get scratched up noses and chins.
But sometimes small children are far more traumatized by the sound of water popping in hot oil on the stove all the way across the kitchen of an evening than they were earlier in the day when their mother ran over them with with the stroller.
I will leave you to think about what an amazing imagination I have to come up with such a hypothetical.
Seriously, despite his VERY rude awakening, he needed only a good hug and some gentle wiping of his face and he was happy as ever. I, however, needed to hug him a little longer, and again every time I looked at his face for the next few hours. And he was hysterical over the sound of the oil popping.
