The whole experience got me thinking about how people are all so different and yet all so alike. The woman had said someone was screaming like a banshee, but before she even said "banshee" and had just said "screaming like," my own brain filled in the word banshee and out it came from her mouth, even though I am clueless as to what a banshee is and why it is always screaming. I wondered if the woman knew the answer to either question.
As for the man, I couldn't imagine what possible reason one could have for walking around looking so ridiculous, and so when I got home I searched online and found that there is a club for men with such mustaches, and a Facebook fan page, and all sorts of apparatus for taking care of them. Apparently they are very popular with a lot of men both here and abroad, although I can't imagine why since they look silly and require so much care, what with the washing and waxing and shaping and trimming. It's sort of like wearing a pet on your face.
As for the banshee, it turns out it's a female supernatural being in Irish and other Celtic folklore whose mournful wailing, screaming or lamentation at night was believed to foretell the death of a member of the family of the person who heard the spirit. Or else maybe she just saw a man with a dumb handlebar mustache.
