I think the most important thing is for us to be real with whatever we are feeling and to not give our feelings away in order to spare someone elses feelings.

We can be happy when someone is sad and still be empathetic and compassionate towards them and their sadness.

If we give our real/true feelings away in an attempt to not have an impact on someone elses feelings, then we are not only hurting ourselves, we are being less than honest with ourselves and others.

Easier said than done, I know, but it's imperative to allow our feelings and the feelings of others to simply be what they are.
