Hello everyone, this is my first post here in this forum, and I registered mainly to get opinions on something that happened, that to me is unexplainable.
I was at a ribbon store in our area, the store is fairly small, but was extremely crowded on this day.
The ribbon is on rolls suspended from the ceiling, and everyone just measures out their own ribbon, and pays up front. The reason I am explaining that, is so you know that the people are in close proximity to one another.
To the left of me there was an older gentleman measuring ribbon, when 3 girls walked by us, one of the girls was pregnant, she looked to be in her 20's. The other two girls were in their early teens.
When they passed the gentleman, he said to the pregnant one, "your little one just said "Hi, my name is Josephine" to me". One of the younger girls said, "Oh my God, that's what your going to name the baby" . The pregnant one looked at the man, and said, "Excuse me"?..he said, "When you passed by me just now, your little one raised her hand, and said "Hi my name is Josephine" . He turned back and started measuring his ribbon again.
The three girls were staring at the man, but then turned and started looking at ribbon. The pregnant ones hands seemed to be shaking as she took the ribbon in them, it sent a chill up my spine. This all happened in a matter of minutes. The pregnant girl was visibly upset, and the three of them turned to leave, but she went to the man, and asked, "Did she say anything else to you?", and he said "no, she just raised her hand to me when you walked past, and said "Hi, my name is Josephine, that's all". and the three girls left.
I have only posted this in one other forum, but the responses I received were not too gratifying. Of course, I don't know what it would take to make a response satisfying, but just wanted a bit more input than what I have received so far.
Most of the results in the other forum went about explaining how this was very logically explainable. Such as the man had seen the three girls at an earlier time and overheard their conversation, and decided to have some fun with them. Which is a perfectly explainable reason for him knowing the information, but if you had of been there, you would have been able to sense, that it was not true. The man and the girls had never laid eyes on one another.
I would like some feedback on what your opinions would be on this situation.
I have been lurking here in the forum a while now, and I would value any and all responses, because from what I have read, you all seem to be, not only intelligent, but also broadminded enough to step outside of the box, and offer your opinions
