Student or Learner
You are a source of confusion. I have a plenty of work to be done today. So, please donít do this again. Thanks.
I want to write this to someone who causes me tension. Is it correctly written, grammatical, and meaningful?
Informally, you could use something like You do my head in. If that is too slangy, how about using You are disturbing/bothering (or other tense/form) me?
You could also say "You are a nuisance".
