If you are going to be on the forums here, you will learn to use the ignore feature. Some people just like to chime is with nothing constructive to add.
Did the guy bump into you as he passed by on the right? If you overreacted and went down because of that, then you are partly at fault. But if they made contact, then I'd be super pissed off as you have a nice groupset on your bike and it all looks to be in good shape.
