It's really not that hard.
I'm not sure where you think it's suppose to be funny, it's a random picture
Selfridges is quite an upmarket shop.
Sellfridges is not.
That fact that you find that fact boring some how doesn't surprise me.
I assume your one of them there foreign types.
Trying to explain would be a waste of time,because you still wouldn't get it.
It would however keep you awake and that would be a shame.
It might also exhaust your limited capacity.
So please go and rest it will be for the best.
