make this sentence more professional: wtf are you saying lol
Hopefully this is what you're thinking of: Thank you for expressing your point of view. However would you mind rephrasing yourself such that I am sure that I understood you correctly?
I don't know if that's my style. Maybe you could make it a bit more casual. I just don't want to hurt people, you know. What do you think?
What about: Hey Buddy, you're funny!
