At the concert...I'd pick a seat in the last row, so there would be no one behind you potentially sneezing or coughing at your head. If you stand up and clap loudly or cheer for your niece during the performance...she'll know you were there, even in the back row.
For the beanbag toss...I'd wear a pair of latex gloves. Kids, especially younger ones around your GGD's age, certainly use their hands for some very gross purposes sometimes.![]()
I got a reprieve on the bean bag toss. The school is in Hendricks County and a kid in that area came down with CV. They cancelled public activities at schools in the county. They declared today a learn from home day as well. Still looking at their options. I suspect more of this will be coming to a school district near you.
