I think it is very significant that in your original post you described the trick that your sister and father played on you. Although on the surface, just a joke, behaviour of this sort can be very damaging, and also says a lot about the way your family is set up. Your father had no place to be siding with your sister in playing tricks on you. It must have been very painful.

However, what I have found, for myself, is that you forgive others not for their sake, but your own. You burden yourself when you carry anger and so on around with you. Its just a dead weight that you have to get rid of to free yourself. Now, when I deal with them, I just try to do the right thing, but I do that from my sense of self respect more than anything else. Do the right thing, and expect nothing. Right action!

Freaking holidays! Shopping is one of my least favourite pastimes. I live in the UK, and they have just imported Black Friday over here. Riots at midnight at the supermarket as the punters fight for bargains. The spirit of Christmas!

Keep your head down, and keep smiling, that's my motto. ;-)
