It reminds me of my travel in Thailand. I had bought a bottle of mineral water in a market as a preparation for next day . Thailand is featuring with hot and stuffy weather . when my father and I visited the Grand Palace,my father was thirsty and asked me to give him the water. He gulped and spited suddenly. “What’s that ？it taste bad. that’s not mineral water. I didn’t know what was that exactly because that trademark are all Thai . The more I can’t figure it out, the more worried my father was. he doubted whether it’s poisonous or not, was it edible? I think at that time he didn’t enjoyed the sightseeing, as a result of the strange water. eventually I asked the guide what was that. the guide made a convulsive laughter. (That guide was in stitches) telling me that was not water but white vinegar. No wonder my father said that’s not water. that’s really an interesting and memorable anecdote.
