The weather can be unpredictable sometimes. Thunderstorm one day and the next day, the heat can drive one crazy.
While I was working on a jigsaw puzzle, the kiddo was sitting on the floor playing with his fire truck and police cars. Then in a moment of boredom and capriciousness, he laid prone on the floor with his face on the floor vent.
He claimed that he needed to cool his face and head and wind from the floor fan or ventilator was not strong enough. He just had his hair cropped short so that he would not perspire so much.
