I know that this message may get to you at a bad time since you’re always busy. You may have noticed I have been trying to avoid you lately. You didn’t do anything wrong though. I have never got myself to reveal the actual reason but the reason is I have a crush on you.
I am aware that it is not a good idea for colleagues to have a relationship with each other. However, it is a feeling I can’t possibly hide. You are my dream boy/girl and I know people like that don’t come around often. I am writing this letter to you because there is a chance the feeling is mutual. No matter how slim that can be, I’m willing to take that chance.
