Answer:
When people are too serious!!
Step-by-step explanation:
Sometimes I will try to liven the mood with a little joke or a little fun, and there is always one person who will be having a bad day and ask something along the lines of, "Why are you trying to be funny?" It really brings the mood of the entire room down, and it gets on my nerves when it happens!
Don't be the person to make other's day worse!
