Hello, Miss. [Name]! When could is used as the past tense of can, it refers to an ability that a person generally had in the past or to something that was generally possible in the past (\"When I was younger, I could run for miles,\" or \"It used to be you could buy lunch for a dollar.\"). Anyway, enjoy your holiday with your family!
