hello
what does " every other day " mean?
Could you use it in a sentence?

If you go out every other day, you go out one day, then you stay home on day two, go out again on day three, stay on day four, and so on.

  • Please file a report on your activities every other day.
  • I don’t think your cat will like it if you only feed her every other day, instead of every day.

What is the difference between tell, speak, say and watch, look and see. Could anybody explain me?
