For me family doesn't just mean your immediate family of mom, dad, siblings, it is extended family too as well as the friends that come into your life. All families are different but true families are families that no matter what happens in life can rely on each other and depend on each other to get through both the good times and bad.
These days families come in all shapes and sizes, some with two mums and two dads or more, single parent families, adoptive families, gay/lesbian families. No matter what, your family are those not just related to you by blood, but those that you can trust, that no matter what each of you are going through you can depend on each other and help each other out.
