Being recognized by little kids... everywhere I go

Usually I am a little paranoid when I go out with Nathan because he is always touching me in public (even if it is touching my waist) and the teacher in me freaks out if some little kid seems me with him. Kids seriously look SCARED when they see me anywhere, after all teachers live at school right(pretty much though)?!?! But it is funny all of a sudden the most active or talkative child just turns mute when they see me outside of school, ha ha. And if I see any little kids looking at me, whispering, pointing at me I know they know I am a teacher and I work at their school. I might not recognize them, but they know who I am, some even by name.
Yesterday at Wal-Mart I thought it was funny that there was a little girl that was running passing my aisle and I looked over and hardly caught a glimpse of her but I knew she was a kinder girl. She stopped in her tracks after she passed me and took a few seconds before she peeked around the corner to see my face again. She peeked and I waved, and she said "Hi Ms. Serna" and hurried along to her Mom at the next aisle and I could hear her tell her that "Ms. Serna is here, Ms. Serna is here". I didn't know her name nor could I place her but it was funny to me that no matter where I go... I am bound to run into kids that know me. So do you blame me for freaking out some... no P.D.A and looking crappy when going to to grocery store because someone is BOUND to recognize me....
