Barbaric understanding

Yesterday at lunch, a friend was telling us about how the place where he parks his car always gets flooded. (It has been raining a lot recently.) He told us that he would take off his shoes and socks before getting into the car. 

Someone joked about how he could get rubber boots instead, and one of the others suggested stilts. But they didn’t know what stilts were called in English, so they looked up the Chinese words. As they were spelling out S-T-I-L-T, I reminded them that the S was usually needed because we use stilts in pairs.

And independently of each other, two of them remarked that if we were to use stilts to hit someone, we would only need one stilt.

Wait - Why am I friends with these barbarians? 😮😅😂
