If you really needed help or whatever and I was around, I would help you no matter what whether I had the time or not and would never ask for anything in return except for that maybe someday you could pay the favor forward.
I am a Senior Citizen that was brought up in an age where people actually helped each other and never wanted anything in return. Things were different back then than they are today and that's sad because people aren't all bad and many would love to help out where needed. Today's Society has ruined many things for the younger generations.
