I am interested to know if anyone else here uses a "safe word" when they are traveling. When we are on a trip, or any other time for that matter, our word is hippopotamus. This means it is time to go. Sometimes when Sarah is shopping I never know for sure when she is ready to leave, or just wanting to use me as the bad cop. She has a hard time saying no and then walking away. Then at other times she whats to use me wanting to leave as leverage to bring prices down during her bargaining session. A few times over the years she has said "I was ready to go" after spending too long with a pesky street vendor. So now when I hear anything about a hippo, I know. This plan has worked out well so far, and think it will continue to. A trip to Africa may throw a kink in plan, but until then we plan to keep using this strategy.
Would love to hear what others do, if anything.
