Fluffy childcare
This is one of those eavesdropping occasions where you really do need a lot more information to even start to make sense of what is going on. The story could go off in so many different directions. Firstly, who are they talking about? Is it another goat, or maybe a sheep who needs a little diversity?
Or does your brain jump to the same place as mine and assume that they’re talking about letting their kid hang out with the kids (I know, that is a terrible joke.)? Secondly, why does said goat, sheep, or child need to hang out with the goats? I have far too many questions and I’m considering DM-ing the guy who overheard it!
