There is a woman in my office who always comes to borrow my phone charger, and at first, I did not see anything wrong with it. But over time, what started as borrowing has slowly turned into entitlement, and that is where my problem is. Because she is much older than me, I have to be extremely careful with how I handle the situation. I cannot speak anyhow or react the way I normally would with someone my age, because I do not want to be tagged rude, disrespectful, or proud. So I keep enduring it quietly. It has now reached a point where I literally have to go and borrow my own charger from her. Imagine walking up to someone to ask for something that belongs to you, and instead of simply giving it back, the person is now asking questions like, “How soon will you return it? My phone is not yet full.” At that moment, I usually just laugh, but inside, I am boiling. Sometimes, I need my charger urgently, but I still have to wait because she is using it. Other times, she will collect it early in the day and keep it till closing hours, like it is now her personal property. I honestly feel she is doing this intentionally so that I will get tired and buy another charger, but I do not see why I should spend my money again because of someone else’s behaviour. What annoys me the most is that if I stop lending it to her suddenly, it might turn into a bigger issue, especially because of hierarchy and age difference. Office politics is real. Please, I need advice. How do you politely set boundaries with a senior colleague without creating unnecessary problems? Or should I just buy another charger and save myself the stress?
