Hey

Yup they like it when you touch them...but only humans (sorry). You see, on your skin there is a lot of bacterias invisible to the human eye. Actually you are covered by them and they live on you. But its not the same bacterias that lives on the plant, so if you tought them and manipulate them too much you can transfer some of the bacterias to the plant and cause diseases and this can easely kill the plant. But you need to scrub the plant, fold the leaves of just pinch any parts. But if you just gently touch it and dont apply pressure on the touch you can avoid the diseases.

Hope the will help see ya have fun and peace!
