Because you've had a bad day

I was in St Ives tonight playing with the concert band and had a few minutes spare to do some "People Watching" from the pier. I don't know what the story is here, they seemed friendly as the walked to the shore but in this picture they really don't seem happy.

It reminded me of the Daniel Powter song we are learning in the choir :-

Because you had a bad day, you're taking one down
You sing a sad song just to turn it around
You say you don't know, you tell me don't lie
You work at a smile and you go for a ride
You had a bad day, the camera don't lie
You're coming back down and you really don't mind
You had a bad day, you had a bad day
