I think it is interesting to talk about superstition with another country's friends because many country has different superstition so we are intersting more another contries.
In addition, some suoerstition has effect that it makes us relax, for example, in Japan if we become nervous, we wirte human in chinese character on our hand and swallow. If we can tell it to foreigners, they can relax and communitate to us more comfortable.
I do not belief every superstition so I cut my cail in the night, but some superstition makes me feel happy so that I belief lucky superstition.
