Like gorgor said, Miki, it's definately NOT petty.
Good on your daughter and your son

And they know Mom loves them, regardless of anything else

Maybe you guys can grill out this weekend or do something small to celebrate. I know how you're always cooking. You could make them their favorite dessert. Kids get over things fast. It's us parents that it sticks with.
Last night, I had to choose between my oldest son's band recital and my youngest son's baseball game. My oldest plays an instrument because he's made to by the school so he was OK about me going to the game. My mom and step-dad went to the recital while hubby and I went to the ball game. At one point, Mother called me on her cell and allowed me to listen a bit. That was nice
