Go get the express joke

You went to help your sister get the contents of the courier, and then you felt embarrassed. First of all, there is something wrong with your question. If you go to get the express for your sister, how do you know what's inside? Then you're invading your sister's privacy. You help your sister get the courier, but you can't open your sister's courier or don't go to see it. This is to respect his privacy. So I suggest you either don't help your sister get the courier next time, or don't go to see his courier when you go. This is disrespectful to your sister, so I advise you to respect your sister a little.
