Friends and family are an important part of our life. Being a friend and/or part of a family comes with responsibilities. To us those responsibilities usually involve helping out when needed.
The help could mean babysitting or giving them a ride. It could mean helping them move their entire house. It might be acting as a sounding board for grievances. We chip in when needed or asked (if it is possible).
It should also be noted that we do not do this because we want to. We don't bust our asses for three days straight because we want you to like us more. Listening to five screaming children on a Friday night is not what we consider a good time. We do these things because you asked for or needed assistance.
Want has nothing to do with it. If you are a friend then you are part of the family. If family needs help then we help.
