When somebody says something that is semantically meaningless or completely meaningless in context, I become so unimaginably angry and I will remember it for the rest of my life.

I still remember I was about 15 and a lady was walking her dog in the same sidewalk, and as she saw me she screamed "Come the otherway!" Like I was a threat. I wasn't offended but just by the fact that this phrase makes no sense, and especially in that context, even if she meant "go the otherway" that still doesn't make sense. That just made me so angry that I wish I could just dropkick her right there.
