First, I commend you for doing a job that I just don't have the spirit to do. I relish the opportunity to spend time with senior generations, and I do to the extent possible. But I just know I'd have difficulty developing relationships with these people knowing that perhaps their time is more limited than they or I might think. It takes a special kind.
Secondly, what a great example of how these older generations are active listeners. This skill seems to be lost with younger generations. It's obvious that this woman heard you and zeroed in on your passions while spending time with you. Moreover, you must've made an impact substantial enough for her to be thinking of you and she made it a point to go out of her way to do something meaningful for you. I trust you will forever cherish this, beyond the tangible gift itself.
I'd rest easy at night knowing your patients have reaped the benefit of your character and so enjoyed your comaraderie that they see fit to do something to leave a lasting impression upon your life.
Were I you, I'd consider engraving this piece with the name of the woman who gifted it to you, or at the very least, write a little note to store in its box that reminds you to recall the memory of this individual when you reach for it; a note that reminds you of the lifetime of memories that this woman holds for herself that may be attached to that particular timepiece. It's obvious that she meant it to be worn for another lifetime by someone that showed her compassion and raw humanity in her time of need.
We can all only hope to be of the mindset to be able to do the same as she has done when we encroach upon the finality of life's ultimate adventure.
Wear it it good health, and keep being you.
