To think some people bring out the worst in you?

[Beautifulblue]

I like to think I'm a pretty calm, kind person... but there is 1 person in my life (v close relative) who makes me SO grumpy when ever I'm around them, that they honestly make me a person I hate & don't recognise being. Has anyone else experienced this?

I sure have. A few times over the years. The worst was a young man I used to work with. He was lazy, self-entitled and everything he touched ended up being a disaster. Normally, I very much enjoy helping younger people find their feet and improve their skills, but this wanker was just intolerable. I wanted to rip his fucking head off, and it got to the point that the first thing I thought of every morning is that I had to go deal with him at work all day. Sometimes I felt like my blood was actually boiling with rage over his utter uselessness. Luckily he was fired after 3 months.
