I perfectly understand how people can act atimes. I understand your feeling of being taken for granted. I can understand how hurt it must feel when you feel that others see you only as a resource and nothing more.
Kindness is giving. There are different levels of amount. It's about balance. If you consistently give & never receive back the scale is tipped in someone's "favor". At that point you stop giving so MUCH. If someone responds back with extra kindness and the scale is suddenly tipped in your area, if you respond back it is balanced. Keep in mind the commitment & intensity is the factor. It's a give & receive relationship & you should give & receive mutually acceptable amounts.
It would be a waste of my valuable upvotes that i would have used to reward highly engaging contents and good feedback than to give to others who never came to refuel me with any positive back. Thank you @hilarski for choosing to rewarding content. Its an encouragement to me and so many others who have not been noticed for sometime and hence stopped posting. I agree with you that reciprocation is as important as the relationship.
I am motivated. Thank you so much and i am sorry that happened to you.
