This is not some sicko post so please don't get your knickers in a knot.
Have you ever had an elderly patient for whom your rapport was so great that you have a soft spot in your heart for them? I definitely have. Usually it's the stubborn old coot who talks about his wife as if he still is in wonderment, and the sly one who, when on transport and asked where he is, states "the elevator" instead of the typical "hospital". It melts my heart.
It's not gender based either. Sometimes the little old ladies crack you up. Like when an 89 year old talks about her sex life (ew), or when she tells you a story of her youth and how she got into trouble through her escapades.
I'm not a fan of geriatric nursing, but sometimes I do develop a little old man-crush.
