Possibly not literally allergic but I'll try and compel my dream self to ask one if I have another one. I just know that I didn't see any of them wearing one. At least some of them were also fond of getting drunk and naked and singing this stupid song. I'm sure they were either destroyed or just lost, especially since this was such a blow to the Empire. Can't imagine Rome was a huge fan of people talking bad about it in any way.
Are you nomads? By choice or by circumstance?
I was joking Well I'll be sure to report back on my findings.
