Today I share a 100% true story from my past.
I use to meet my little brother to eat together with him regularly, but any time his friends or others that knew him would meet me the conversation always seemed to go the same way. They would ask who I was but they never believed that I was just coming to spend time with my little brother. Most would insist we couldn't be brothers, but when I asked them why not they refused to tell me why they were skeptical.
That was until the end of the 'year' when I was invited to join them all when when they were going out somewhere special to celebrate one of the last times we would all be together. Again I meet an acquaintance of my little brother who was skeptical of my explanation of how we knew each other, but this time when I asked her why she didn't believe my she gave a good reason for her skepticism while pointing to my chest. I admitted to her that I was impressed that someone was finally willing to gave a reason for their skepticism, even if it wasn't definitive proof; but I still didn't end up giving an explanation to her confusion.
So can anyone explain to me why no one believed my little brother and I, or why no one was willing to explain their skepticism until that last time? Bonus points if you can guess why I wasn't immediately offering an explanation for their confusion.
Some hints to help rule out possible answers, generally ordered form less to more useful:
There is some knowledge that could help to inform this answer, but I decided not to include the knowledge tag as I decided the information was likely general enough to be known; and that one could probably guess at the situation without being aware of the specific piece of knowledge.
I knew why the friends were skeptical, but was intentionally refusing to acknowledge it until they explained.
I knew they may not be comfortable explaining their reasons for being skeptical, but I admit even I'm surprised no one ever gave the obvious answer.
figuring out where we would have met to eat will give context to some of the questions.
The time that someone gave an answer they gave a different answer then the one others refused to give
there was something different about the last meeting then the previous ones which explained why the final person was comfortable giving an explanation for her skepticism.
It was because we were going out somewhere special to celebrate that the final individual was in a position to give me a good answer.
there was a significant age difference between me and my little brother.
I'm not biologically related to my little brother.
