When was the first time you really felt like a grown up (if ever)?

In my early teens, discovering ancestral heritage and the possibilities of romance, I felt I had arrived.  I have spent the decades since then clinging to the glow of what should have been a speedy transition. I realize I have missed some of the essentials of growing up, but do not expect me to carry any guilt when a large number of my peers have also been clinging to priorities of the transition into adulthood.
