Negative nancy is everywhere and sometimes that affect the way you work. I work from home and my surrounding is pretty negative. That also sucks.

you'll soon hear a complaint, a sigh, and that really irritates me.

That is how it always with them. You can talk to them about it and confront them if it gets that bad. You can also choose to ignore them if that's even possible but yes, the older I get, the more I want to stay away from negative nancy.
