Like yesterday I was complaining about the people who put a t-shirt on the wall, today I would like to talk about the people who put the flags on the window or the balcony.
If you live in a small town in your Country, all the flags will be the same. Still, if you are in London, it's straightforward to see that you neighbor and his girlfriend have put out the Brazilian and Argentina flag and we will know for sure if at the quarter-final of the world cup just one of them will celebrate and the consequence will be:
A) they will not have sex that night and
B) probably the next year, one of the two flags on the balcony will look different.
So don't put out flags on your balcony.. we don't want to know your private life.
