I work in an office environment. Our cubicles are partitioned so that each aisle has rows of 2 cubicles side by side with a small walkway in between. When I first started working there a year ago, I became friendly (as a professional courtesy) with my neighbour who sits directly across from me. Then she got a little too "friendly" physically. I'm pretty sure it was platonic (since we are both girls) but it made me very uncomfortable. I started avoiding her but it was hard since she sits beside me everyday. Over the PAST YEAR, I've noticed that she imitates everything I do -- my mannerisms, the way I talk on the phone with clients, the way I laugh, the way I walk, the way I tie my hair up, what I order for lunch, wear the same style of boots. When I get up to chat with other co-workers, she gets up too. When I sit back down, she sits back down. There was even a period where I would get up to use the washroom and I would always bump into her on my way out. In a conversation with another co-worker, she mentioned that imitation is a form of flattery. It is getting extremely annoying and frustrating. I feel compelled to be different from her so I am constantly doing something different, but it eventually gets imitated. I want to focus my energy on work, but I feel like I can't be me anymore. I could see her watching me all the time, observing what else she can copy. I want to confront her, but I don't want to cause conflict at work and draw attention. I don't want to do anything to rock the boat at work, so to speak. But if I continue to sit there and do nothing, I feel like I'm going to go crazy soon. What should I do?
