I had a toddler come up to me in a department store and wrap himself around my leg sobbing "momeeeeee", I think he was lost and thought he'd found his mom. I stood there for a second and then reached down to comfort him, he made eye contact and started screaming. Fortunately mommy heard the screams and came running (he was still clutching my leg), she looked at him then looked at me and as she was prying him off said "you look terrified, you're not a mom right?".
