i have as school friend who is a Cancerous. From childhood he is prone to different physical ailments and he is weak mentally as well. He is   very good at study and cracked through the written portion of the  competitive exams all the times.

I have a cancer friend whom i never got to understand....
She is soft spoken but very irritating to me...
She never harms me but i dont trust her at the same time ...
I am a Pisces.. Why is this happening....

you may ask if they will talk with you more often with reason the Cancer are very wise. @^

Stop concerning yourself with their so called mental disability and begin reasoning with among
proper accord the reason you were not kind with them, regard their physical health (ignored),
and try to reason with yourself instead of protectate ways trying to network around them and:
saying you were not the admonish(ment) of their so called mental fortitude whereas since you
are Pisces you can be envious and then calm.. Actually positively care at all instead of egoist :  worrying about their disability.
