There are several plants in my office and the balcony of my office. Usually there is a lady who is responsible to take care of all the plants in office. One day last week, she told me that the ball cactus is dying. I was shocked. It is placed besides the printer on my left side. The side it showed me still looked good. But the other side, which is close to the door to balcony, it has rotted away. And the other day, when a banker visited, she told me that another green plant on the cupboard in my back did not look good, too. I felt so sorry for them.
I checked internet and understand that they may fall sick mainly due to the previous some chilly nights. And as I seldom opened the glass door, the room might be stuffy, which also made them sick. Even I did not feel good during those days.
People suggested me to replace them by new ones. If I agree to do so, the plant company will throw them away directly. I decided to keep them and see if they can recover. I move them out to the balcony during day time and move them back to room after work.
I have no idea if they can be good, but as long as they are still alive, I feel I can not give them up, even I do not notice their existence most of the time. They have been with me over one year. If I easily give up, I will feel bad about myself.
