Back to the subject: my sincere sympathy extends to the innocent sufferers to this senseless crime.
I'd rather not be speaking of 'The Orange Fool', much less take him or his word about any subject. If I don't speak of him, the time passes a tad quicker and a bit more pleasantly .
In my addled mind terms such as 'subway', 'tube' and 'underground' convey the same meaning, but YMMV (your mileage may vary). Legal correctness and reference to the transit in this case here seem to me to be casual, in my mind.
Out to get some more sun now.
Nods to the down-thumber. May your thumb be caught in a car door.twice.
