Alias Scipio can tell a good story
maybe it was a very windy day and everyone saw what was under his kilt. What a site
or maybe he is over 6ft tall and wears the kilt as a mini then they would see what he was so proud of

Was it a windy day, scipio?
I don´t think it was windy - he said that people looked under it...
"I don't think I have ever worn britches I don't even know precisely what britches look like, I have worn a kilt but I didn't wear underwear so that was not good when people looked under it."
Just trying to imagine how a little girl would have gotten the opportunity to look up under his kilt (and WHY!!!). Surely you would notice and make sure it didn´t get that far!
