DIGNITY has come to mean different things to different people - as words often do.
I propose we look past the oft-surfaced meaning of one being stiff and composed and look at DIGNITY and being 'DIGNIFIED' as a strong belief in oneself, that one is worthy of the best.
Let DIGNITY mean 'what I have to say is important, I will say it when it's important for me to say it, and I will say it in a way that upholds my values & sense of worth.'
In my world, DIGNITY really means I deserve the best treatment possible and will politely insist on receiving.
Alternatively, being DIGNIFIED means I have the responsibility to give the best treatment possible to other people.
