Just Do It!

Feeling hot? Why don't you take your kit off Bro? Sure, just do it. 
Feeling tired. Pah, no worries, just stretch your weary young legs and rest your Nikes on the seat opposite you. Sure, just do it. 
Feeling bored? How about blasting a little tune on your phone, for the whole carriage to enjoy? Actually, bollix to that. That's where I draw the line. The delivery was sufficiently unambiguous to achieve immediate action ("Hey folks, can you please switch off the shite music? You can listen to it as much as you want, when not on my train")
