 I liked a girl in my office. I used to smile at her when she was passing by and then she also started to smile and chat. Sometimes she laughed too but when I tried to chat on WhatsApp she said she wasn't interested so I stopped. Then I started calling her on the office phone because she sits in a different department and she talked to me about her projects etc. After two months I called her and I told her that I like her and she said she doesn't want a relationship so I said no problem it's okay and I did not message or call her after that. After one week however our HR said your recent activity is affecting our female staff and warned me of strict action but I didn't say or do anything wrong. Okay let's break this down. You like a girl she smiles at you so you figure that she likes you back. That's okay it's an honest mistake it didn't happen to anyone but then she tells you that she's not interested. You however choose not to hear that no you stop WhatsApping her certainly but now you start to call her on her office line and she figures that okay I've told him I'm not interested I've cleared the situation so she goes ahead and she talks to you about her projects not her personal stuff but you once again take this as a yes. The call to HR was actually very important because who's to say that you would not have misunderstood the same thing again like if she smiled at you the next time or it happened with some other woman in your office. I know you feel really upset right now but I want you to take this instead as a life lesson because you will be for many many years to come working with other women very closely in your office and understanding boundaries is going to be the very first step in your development.
