Yes, I think from the smiles in the picture and the story itself, we may assume that they are all three blessed with an indestructible sense of fun.

We are, however, a varied world, and the more sober-sided and less sentimentally inclined among us, whose delicate sensibilities may have been startled will appreciate the recall to common sense you have so kindly bestowed upon them.

You put it much more courteously than I might have.

Which I'm speculating is why the OP used the expression "drew a gun on me."

In the US, to draw or pull a gun "on someone" implies that the holder of the gun is threatening or intending to shoot said someone.

Unless I'm mistaken, the OP means that the guy merely produced the gun and showed it to him.

But because neither event occurs with the same frequency in the UK as it does in the US, they probably don't need such specific expressions.
