Well, if I'd had an extra umbrella I would have offered it.
As it was, we got really friendly squeezing underneath the one we found in the trunk of the car. Of course, it was tough, since we had put all the extra clothes that were also tossed in the trunk. We were the couple wearing shirts, sweatshirts and a jacket with a towel and/or blanket wrapped around our legs trying to keep our posteriors dry on the cement bleachers.
