I started my job last year and almost immediately, I noticed that one of my older male coworkers seemed very into me...everyday he walks by my office and stares at me through the glass window. Not just a quick glance...but a good 4/5 seconds of staring. When I pass by him on my way in, he smiles, lowers his voice, and gives me "that look." I have also caught him staring at my chest before while I'm walking right past him!!! I found out today that he's been married for 10 years and has 5 children!!!! Help!!!
