I am STUMPED!!
A moment to me is a short period of time, like in "Wait a moment." I think of a moment as being a second.
I have no idea what is expected of me in response of this title. Since it has an "A" in the title they may be looking for a special moment.
No one moment in my life can stand out as the most outstanding and wonderful. There are too many that I treasure.
If they are looking for a special moment. I have hundreds of them, maybe a thousand.
Birth of my children and grand children. Christmas', holidays, trips, vacations, graduations, sunrises, sunsets, marriage, flowers, animals (small), good golf shots, kisses, hugs, babies, good sermons, good sport games on TV, traveling, praying, etc.
I could go on for ever but I am boring even me.
On reading that list I see only good moments. If I have bad moments I do not dwell on them.
I treasure my life and try to enjoy every moment that comes my way and am thankful that I am able to experience them.
