It is not what you wish to do in that moment but it might make an ignored person in a crowded room feel less alone, and so you volunteer your smile.
it is not how you planned on spending your evening but your old neighbor lives alone and badly needs to connect with another human being, and so you volunteer your time.
it is not where you want to feel, your day was crappy but your friend has gotten the best news of their life, and so you volunteer your joy.
Life has been unfair, you trust nobody but someone looks deeply into your eyes and wants to make it right, and so you volunteer your love.
Most times, we really do not want to do what is expected or demanded of us, but sometimes we have to try.
