Went back to ikea last night, and bought, finally a book case.
I put it on the trolley, its length is 170 cm, the trolley is about a meter, so there are 70 cm hanging around making it all very complicated. I bumped into this lady and hit her, I apologized immediately, it didn't help, it still hurts. She gave me the nastiest look ever. I can understand her being upset and in pain. But I cannot find a reason for the tiny bits of hatred that sparked from her eyes.
