Need some advice. I have a co-worker who is REALLY pushy, rude, and accustomed to getting her own way at all costs. She keeps inviting herself to come over and use my pool. I let her come over once, while we were out of town, on the condition that she NOT bring guests, and that she add some chlorine to the pool while she was there. She brought guests, and said she did not want to add the chlorine because she was not "comfortable" doing that...even after I taught her the correct way to do it. I feel like she is simply using me, because i have the pool. I work for Social Services, and deal with people all week, and my husband and I like to have time alone together on the weekends. This girl is SO pushy, she caught me in the office earlier this week, and TOLD me she would be here today at 10 am to swim. I said: "Uhhhh.....noooooo.....we have things to do and i will CALL YOU when and IF it is convenient for you to come over. Quite honestly, I do not want her over here at all! She's OK, but we have nothing in common. (And I don't like her pushy personality!) The last time she was here, she even took the liberty of buying a pool float for herself, and storing it under my deck with the rest of MY pool stuff. LIKE SHE LIVES HERE! I just want my private time uninterrupted by this pushy woman. Any ideas as to how to get out of this situation tactfully??? I DO NOT like to hurt people's feelings.
