Am I a bad Soccer Mom?

I ask this question because my son's soccer team played against a team this evening and all that went through my head was "crush them!"
Part of my aggression had to do with a few kids on the opposing team that my son used to play with a few years back who's parents decided to leave and not talk to anyone anymore.  Oh yes, it was that childish and even after repetitive emails asking why these 2 families had cut off communication... we still to this day have no idea why.   Seeing them at the game today actually created a little anxiety for me as I was conflicted on how I truly felt.
When this all happened 1.5 years ago I was so hurt and confused.  I didn't understand why they cut off communication as we had been friend for many years.  We never got a reason so after a few months that hurt turned into irritation and a bit of anger.    I wasn't even sure how I would react if I actually came into contact with them?   Luckily only one of the husbands came over and said hello.  He was gracious and we chatted for a bit.  It took everything in me to not react and say "wtf?"

Soooooooooo when our team scored the goal against their team was I excited?  Hell yes and I even got up and did a victory dance!!  It felt good, real good.
So thank you boys for giving me a reason to cheer, be proud and rub it in the faces of those meanies who treated their friends like dirt.   I feel so much better now :)
