I agree, as an identical twin (partially inversus situ) — some examples: opposite hand-dominance; our optical Rx was once exactly opposite; intro/extro -version

I agree, as an identical twin (partially inversus situ) — some examples: opposite hand-dominance; our optical Rx was once exactly opposite; intro/extro -version; engineer/stoner; life outlook/perspective. We have taken completely different life pathways, and yet still enjoy each others' company. Knowing that I will precede as "Algernon" from "Flowers for..." makes me immensely sad for "Charlie" [Twin].
