What drives me mad is when the kids lean up against your car with all their coat zips and buttons scuffing the paintwork.
I've never known a collection of people so deficient in common sense.
Another (slightly related) example of stupidity, we were out in FS one day when a thunderstorm came out of nowhere - masses of rain, it came down in buckets.
Some of us saw it coming and had just enough time to run back to the car.
Others just stood like post boxes in the rain, getting drenched through, even though there were phone boxes and bus shelters nearby.
One sister just stood sobbing as the rain poured through her coat and clothes.
That was the end of FS that day and the soaked through ones were looking for lifts back into town.
Not in my car thanks, soaking the upholstery. I shot off before they got near enough to ask.
