So I am on a first date. She was quite the silence filler which was great. We both agreed we had an awesome time. At the end of our evening as we were about to part ways the silence finally happened. She started batting her eyes and gazing between my eyes and lips, smiling and biting her lip, it was absolutely adorable and I knew what she wanted so I went for it. Anyway 2 days later we are talking about it and I told her how adorable she looked doing all that and she told me she had no idea she did it.
Is it common to give the "Kiss Me" signal subconsciously (or any signal for that matter)?
