Well, I did try to keep it at my place, but my room was much too sunny and the tree was losing all its leaves. I tried keeping it in the living room, but it was really draughty and the temperature was always changing.
I took it to his mom's house and their living room was sunny but the light wasn't directly oriented at the plant, and the temperature was rather stable. I do admit the poor plant was saved by his mom

.
But then... he did keep it.
Oh, well, at least I'm not a plant murderer, lol!!!
