Someone asked that question who couldn't figure out what to say was probably trying to figure out what kind of lie appropriate social behavior requires him to tell.
Filtering out those kinds of people when you seek friends is useful.
But "those kinds of people" here means "people with social skills".
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
