Did the elderly gentleman cross the line?

Today I went to the mall in hopes of finding a new blouse or dress for my brother-in-law’s wake this weekend. I searched and searched but was unable to find anything that fit or was appropriate. Becoming increasingly frustrated, I decided it was time for lunch. After purchasing my quick and not too healthy lunch, I walked over to a seat that had a lovely sunbeam shining down on it, and asked the elderly gentleman at the table if he minded that I joined him. He said no, his wife wasn’t due to join him for another half-hour, and there was still another seat available.

Immediately after sitting down, the elderly man started a conversation with me, and as per usual, he asked me why I needed a cane. I gave him the short version of my health history and basically explained that even though I look healthy, I was far from it. After about fifteen minutes or so, he leaned forward, smiled, and asked “if I could still perform my nightly duties?”. I laughed, and responded with a “yes, and added I did have to be careful”. After that, we continued on with our conversation about my health waiting for his wife to join us.

When I returned home, I told my husband and the teenage boy (who just happened to be in the kitchen at the time) about my interesting lunch. The teenage boy responded with a “WTF”, whereas my husband laughed.

What do you think? Did the elderly gentleman cross the line? What answer would you have given?
