Masala mint soda is something I've not heard of before.

I hadn't seen it before Martsa. It may be a standard feature of Tibetan restaurants, however. I haven't been to very many.

If I may ask, have you any particular customs for observing the equinox?

Not usually, but I try to note its occasion. It's a turning point.

Another had a pony vomit on some poor child, which would be funnier if it weren't for the fact that the equine inability to vomit sometimes kills them.

. . . Thanks for letting me know.
