Joe, you could have a sign and/or wave to us, but only if you want to. You might want to stand on the sidewalk to do so. We don't need you getting squashed by a big truck.
Although… that would be a fascinating Beatles Bible moment if a slow, yellow lorry blows the horn at Joe, to get him to move out of the crosswalk. The lorry driver might yell "What, do ya got no where to go!?!"
