You know how sometimes a discussion can go off on a crazy tangent, make lots of crazy turns? You don't know where it's going, and you don't know how you got there? Your discussion has gone down a Rabbit Trail. (Sometimes I like to call them bunny trails when I'm feeling silly.)
You would never use that phrase to describe a leisurely trip when you explored a side path and had an interesting adventure. That's more like taking the road less traveled by, which is a literary reference to a poem by Robert Frost, "The Road Not Taken."
And we reach another week of idioms. You may or may not know, but I have been posting a link to the new entries on Facebook. Do you think that I should continue to do that? Please, leave an indication either here or on Facebook. Thanks! Have a great weekend! :)
