What really makes you angry?

I am very irritable especially when there is a lot of work to be done. I hate when the devices make a continuous annoying noise, especially in summer when I have to use a fan and they are everywhere. I do not like conditioners as I think that they are harmful to my health. I have even started looking for the quietest fans if such exist. Have found some products at https://silencewiki.com/reviews/the-quietest-fan/. I think I'll buy one of them because I'll have a brain attack as it seems to me this summer I'll work from home because of the lockdown.
