Not a toy

Jon and I took Henry to Zion for the afternoon over the weekend. We stopped for a bite to eat on the way there. We ordered, sat down, and started eating, trying to keep Henry entertained. He had been super fussy in the car and was not happy with the scenario at the restaurant. Henry doesn't like that there are things that we eat that we cannot share with him. So Jon put Henry on his knee and was bouncing him gently and talking to him. He was having nothing to do with at high chairs at that point. And then Henry started looking around and people-watching and some of the people were watching him right back and smiled at him. That made Henry giggle, which made this lady turn around. She looked at Henry, then Jon and I, then back at Henry and he gave her a great big smile. Then the lady's eyes got all big and she exclaimed, "Oh, he's real!" And upon seeing our confusion, went on to clarify, "I thought he was a doll!"
Because Jon obviously looks like the type to play with life-size baby dolls.
I assured her that Henry is very much real, and went back to eating. But a few minutes later, it must have still been on the woman's mind because she shared, "I think I must have thought he was a doll because of his eyes. So blue."
She kept looking at me, waiting for a response, so I said that he does have great big blue eyes, smiled at her, and went back to my lunch.
Not two minutes later, another couple walks in and this woman starts waving and smiling at Henry and then calls her husband over to look at him. She then starts talking to Henry as if his parents are not there. You know, mostly the usual, "Oh, aren't you so cute?! ... I could just eat you up.... Well, aren't you all smiles?" I honestly don't know how to respond to that. I mean, she was talking to Henry and not me. Was she expecting him to answer? And then as I got up to go to the restroom, she started talking to Henry again and asked him, "Do you think your mom would mind it very much if I took you home with me?"
Since I was walking right past their table, I did answer that one. "I'm pretty sure his mom would NOT like that at all." I said it with a smile, so that was ok, right? What would you do? She was kind of talking about kidnapping, after all.
I blame our odd dining experience on the location. That's what we get for eating in Hurricane.
And for my parent friends out there, do you just get used to being treated like you are invisible or do you insert yourself into the conversation? But even then, what do you say besides thank you? Do you gush stuff like, "Oh, I know, he's just toooooo cute, isn't he? Can you believe those sweet chunky thighs?" Or do you share something more truthful like, "Lady, you don't know the half of it. Do you know how much work it is keeping this baby happy, out of trouble, and entertained?"
