This happens to me often. I will meet someone at uni or through work and if I do not enjoy their company, I don't really want to spend time with them outside work or uni. The problem is that some of those people just do not take the hint to leave me alone. They keep messaging me to meet up and I keep saying no. I try everything to get them to leave me alone. Barely reply and ignore messages. They just continue to bother me. I often wonder why they do not take the hint. The reason I don't want to spend time with them is usually because they are rude or unkind. Anyone got a clue as to why some people just can't take the hint to go away?
