Wow, my sister makes herself really angry about the tiniest, most ridiculous things. It actually breaks my heart to see her in such distress, of her own making, not having a clue what to do about it.
I love my sister, but she sometimes makes herself very difficult to tolerate. She also doesn't believe us when we tell her it's distressing to see her so angry and upset; she says we're lying to make ourselves look good.
*sigh*
