What is the consideration

 You have to understand, nothing comes free in this free world 

or free country or enlightened society of ours. 

When you buy something you naturally pay for it. 

But if someone gives you something for free, the first question

 you have to ask yourself before accepting it is, 

what is the consideration. 

If it's love and affection it's ok.

If it's anything other than that you have to understand you'd be 

forced to compromise on your principles on a later date.
