I really don't know if somone of you had previously mentioned something about the English sayings or Proverbs
Anyway, let's start of with this good proverb and I will put it in an example and i'll add a usage note to make it clearer...

Example

what you did is your job no more no less....please stop "making a mountain out of a molehill

"make a mountain out of a molehill"

Usage Note:

make a mountain out of a molehill" this is basically what we are after.....you say this proverb when you see somebody exaggerate what he has done even though it is normal and does not need all of that fuss
