Well I wouldn't go as far as calling you a dog....and well you should know by now that if people get used to you helping them out
in the future they'll just demand help instead of asking for it, or if something goes wrong you're the first person that's blamed. I know enough about that from experience. But if you really are tired of this take the first step because stuff doesn't work itself out.....well from my experiences it doesn't. Good Luck of your journey
