Grrr ... siblings

I had a fight with my sister who said that I needed to respect her decision about certain bs things that really don't matter much in the scheme of things and I just had to end the conversation because it's so the pot calling the kettle black. Hah! Like she ever respects my opinion about stupid bs things that don't matter! I know it sounds stupid and it is, but it's also frickin' frustrating!! Arrrgghhhh!!!
