Cách sử dụng
The expression "every so often" means that something happens from time to time, but not regularly. It is used when you want to describe something that happens occasionally or intermittently, but not on a set schedule. For example, you might say, "Every so often, I like to take a break from work and go for a walk." This means that you don't go for a walk every day at the same time, but you do it every once in a while when you feel like it.
