ARGH! EVERY single thing that goes "wrong" in this house is my fault!

DC has a virtual class this morning that they have been begging to take for almost a year. Now they are upset because they have to do this on a Saturday morning (the first class is not going to be fun)! The technology wasn't working so DH is mad because he had to stop everything to fix an wireless issue he has known about for 12 months (I though it had been fixed last year). AND DH wanted to take DC out for lunch, but the class is going to make it a very LATE lunch. They are both now mad at ME!
