“…wander to somewhere along the route of the march. You'll both be very welcome and have an excellent time. :o)”
Two or three years ago I was unfortunate enough to be “somewhere along the route of the march”, not wandering but trying to go about my business. I’m not sure whether or not I was welcome (I would like to hope I was not). This was because my priority was trying to circumvent the many hundreds of assorted weirdos and creeps marching along with their faces and hair painted a variety of colours and to make my way through the throngs who had, inexplicably, turned out to witness the lunacy. An “excellent time” was not quite how I’d describe that experience and I was (considerably) late for an important engagement.
I don’t quite know why people feel the need to take to the streets for matters such as this. Surely they can sit at home and “Tweet” to each other or send “Selfies” to their friends or whatever it is they do. If they really see the need to gather outdoors there are plenty of places they can do so where they will not inconvenience people trying to conduct their lives in one of the most congested cities in the world.
