And people choose how they feel about it. Some people may like it, and others may not. It's a wash. Who cares?
You do. Because you are the one who brought Nole and his winning celebration up and went on stating how much you don't like it. You say 'live and let live'. You clearly don't practice what you preach. If you did, then Nole's celebrations would have not been a problem for you because what Nole does after winning a match is not a crime nor it is illegal. In fact, it's perfectly normal.
Truth is, that is if you are really interested in it, you don't like Nole regardless because he is an imminent threat to your favourite player Nadal, who btw can do nothing wrong in your eyes. Nole is someone who has denied Nadal from winning several Slams and your negative feelings about Nole stems directly from there. Now you can write a dissertation about how it ain't true but I will be last person to buy it as I already know what the truth is. You use Nole's celebration as a smokescreen to cover your ultimate feelings about him - a man who's standing in the way of your man's ultimate success. You say you don't care about that but you care more than herc does.
