You actually unplug your stuff during a storm? I've never done that.
My grandmother does it as well, since that lightning struck and destroyed all electronics in the house, even the wiring, Pieces of brick from the chimney flew over 30 meters far. Was quite a bang she said.
Pros: Warmer weather, some more colour outside, a bit of a tan, hot girls in short shorts, no need for gloves.
Cons: The evening rains, storms, hayfever, wasps, mosquitos, flies, farmers fertilizing the fields, heat a night making it hard to sleep, sweating during the day making you sticky, sunburn
all i can think of now, will come up with more later
