That's a human tragedy.
Many men are hesitant of being too close to other men.
For several months I volunteered at a nursing home in Cincinnati, helping the activities department help the elderly who were alone. I was asked to get conversation going. I found out that with men that's extremely difficult especially where these people also had geriatric diseases but with women it was easier to generate conversation. A friend is someone you can trust and depend on. A friend will often overlook obvious mistakes, but if he or she is a good friend, a supportive friend, he'll make suggestions.
