Why is no one allowed to see Colin? Why does his father rarely visit him?

Colin is unhealthy and spends all his time in the mansion. It is feared Colin will get sicker if he is exposed to more people. Mr. Colin cannot bear to look at his own son because Mrs. Craven died giving birth to him. Colin is pretty depressed and lonely so he cries all the time.

Nobody is allowed to visit him because he is rude and sick.Mr.colin cannot bear looking at his son because his beloved wife died giving him birth and colin's eyes are similar to Mrs.cravens eyes, so when Mr.colin feels like looking at colin he goes when he is sleeping.Because it always reminds him of his wife.
