There's a saying that "the help we render to those who can not pay us back is the rent we pay for our stay here on this planet".
This is deep!
Well....i help when I can, for those who seem to want to be pests, I just help them halfway and not fully so they learn not to be too dependent on me....i just help if i can mostly.
There are some people I'm really trying to shake off, the problem is: once you help, they think you have arrived and doesn't have obligations too so they keep coming back always.
