In this episode of All Ears English, Lindsay and Michelle discuss the idiom "cold feet," which means getting nervous or having second thoughts before a big decision or event. They explore its usage in various contexts beyond weddings, such as starting college, a new job, or even making new friends. They share personal experiences of getting cold feet and offer alternative phrases like "having second thoughts," "chickening out," and "having doubts." The hosts also discuss strategies for dealing with such feelings and introduce a poll question for listeners about whether they experienced cold feet before their wedding, and role-play a scenario involving bungee jumping to illustrate the idiom in action.
