Adequacy means the fairly equal values between the two. Nevertheless, adequacy is decided by the parties themselves, as everyone has their different definition of fairness. In the other hand, sufficiency is real, and must have actual values in it. Even if there are bad bargains for any party of the contract, the contract can still be valid.

However, if I called my friends with the exact same request, then it would be a different
