In past years I was so nice I really allowed people to abuse my niceness lol. Not in the past few years though, my spine suddenly developed and people have been taken aback when I stand up for myself. Though I feel I still qualify as a nice person:)
I can be if I'm dealing with someone who is the same towards me. I was definitely NOT nice to a young man who wanted to use the same washing machine out of which I was taking my clothes. He kept hovering over me, invaded my space and when I asked him why he was crowding me, he said I was taking too long removing my clothes because I was taking it out one item at a time. although I was half finished. For clarity, I had no choice, that machine twists your clothes so that every item is wound around every other item, so you can't just take it out. In addition, some clothes don't go in the dryer so I separate those out. I can assure you that my response was not nice. I was nice enough, though, not to come down when his clothes were on spin cycle and empty a bottle of ketchup into the washer.
