Summarize the following text: Relationships are of different kinds. Some are familial and intimate, formed by blood and by marriage, some are social like the ones we have with friends and some are made in school where we form close bonds with classmates and teachers. Relationships can also be fostered in workplace, which may quickly change from professional to social. There are relationships also between human beings and animals, between children and their toys that they cannot part with. All these relationships keep us close to each other and provide us all kinds of support, love and affection. A person who has no family feels the pains of loneliness and isolation. There is no one to laugh or cry with him/her. When we share our joy with someone, it simply redoubles, and when we suffer a loss and someone shares our sorrow, it lessens. Relationships are thus needed for our emotional health.
