To be honest I think the answer to that last question is, we shouldn't do it where it's more comfortable because when you flush the toilet it bubbles up and threatens to overflow, and if that happened you would have the problem of what to do with the turd that is sitting on your bathroom floor. If of course you go outside there isn't much that a nice hole and a few leaves won't fix. But if you are outside you may have the neighbours taking a peek, so you have an important decision to make, turd on floor or turd on show. We live in tricky times.
