Pisces is a water sign. Pisces is very introverted. In fact, in their minds, no matter what they look like, as long as they are deskmates, they will be extremely happy. The deskmate loves herself anyway, so Pisces cherishes this mutual affection between deskmates. If Pisces meets a funny deskmate, he will be infected by them and become more and more outgoing. So you can see if you are funny in life, so you are infected with each other!
I don't think it's a bad thing to snitch. We can understand each other. If she typed your report, then you can also type his report. It's really nothing. Pisces people are just more emotional about the people they care about and like to tease you. They don't care much about what you say. To tell the truth, that man is unwilling to talk to you. So if you can, you should treat this Pisces deskmate well, because he will bring you a lot of fun in life and make you have endless fun!
I have a deskmate who used to be Aries. People in this constellation are also very happy, and there is no shortage of reports, but I have no resentment, because it is really fun to be together, and youth plays with each other!
