Margrave and the Curse of the Angry Ninja

Over the weekend my wife and I went to a supermarket late one night to do some shopping. To be honest, I am still a bit on guard when we go out and on this particular evening it was further exacerbated by another encounter with the muttawa.
Anyway, as we walked down one aisle we passed what I assume was a mother and daughter out together. The mother was in full ninja attire whilst the daughter was more “Lawrence of Arabia” as she’d covered her hair and pulled a scarf about her lower face.
As we passed them the daughter stared at me. Wondering if she’d look away, I stared back. She didn’t and because her face was covered I have no idea what her expression was and what the stare was meant to indicate. It could have been flirtatious, it could have been disgust. I don’t know.
Later we were deciding what to take from a deli counter when a movement caught my eye and I looked over to find the same girl re-covering her face after trying some food. She immediately nudged her mother and said something whilst pointing at me. Her mum then fixed me with some sort of ninja death stare. I was transfixed. I felt like I was an innocent man being accused of something terrible (leering, I assume?!) and I felt like staring back at her would prove me a leering scoundrel, whilst looking away would prove I had a guilty conscience.
In retrospect winking at her was probably not the most sensible reaction. To be fair I was at a total loss about what to do. I knew she couldn’t talk to me, hence her reliance on the death stare. I didn’t feel like I could talk to her either. So a stupid misunderstanding became this surreal silent staring contest that no one could win. All we needed was “O Fortuna” from “Carmina Burana” playing in the background to complete a scene of comic genius.
I don’t know why the girl insisted on creating the situation but it upset me because I was obviously being accused of some cardinal sin and I had no way to resolve it. I guess it serves me right after complaining about the locals staring.
It was another crazy experience. I am not a big believer in coincidences, but can you guess what the deli counter was selling? Nuts.

Oh... and I was so upset I didn't even complain when the cashier robbed me of my change.
