How do you keep from bringing your workplace problems home to your family?

[I Love Fun]

There are people at work who really get to me and I want to just go home on Friday and enjoy the weekend with my family, but thoughts of my co-workers and what they did or said to me that day keeps popping up in my head causing me to be a little cranky. HOw do I Not let it bother me. I just want to enjoy my weekend with my family, but the workday trials just really get to me.
Any advice appreciated. Thanks.
