Life is about balance, trying to attain the most wanted equilibrium everytime for everything. So when someone give you something, there is a likelihood that you will reciprocate. However, nothing, not a single thing in this whole world is necessarily reciprocal. You name it: trust, love, friendship, favours, kinship, relationship, blah blah blah. Thus in the end you just have to heck that bloody balance thing and go with your heart, mind, and conscience. (:
