I know how you feel. I have a rotten older sister too and I hate it when people go on Facebook to brag about how grateful they are for their families. It always feels like they're judging you for not faking positivity. Once I got stuck at a church event where the person in charge tried to make me express appreciation for my sister and I just refused. They wouldn't move on and kept pressuring me to talk about my sister and acting as if I had done something bad.

I didn't know there was a sister's day. I thought the public displays of superior grattitude on Thanksgiving was enough ego stroking for the pious. And while I'm sorry that your sister gave you such a bad time, I also feel better knowing it didn't just happen to me. And don't stress about posting on Facebook for Sister's Day. Facebook socialites are probably too busy counting their likes to notice whether other people are posting anything.

I know how awful it is when bad memories are triggered. Sometimes they last for years and you keep feeling the injustice that your sister was never punished. Just remember that her actions proved that she is a stupid and inferior person and that deep down she knows it and will always worry that people will find out she's a bully. You can go through life knowing you're not a worthless bully.
