Im not perfect, but I enjoy photography

In any line of work, if somebody, in a rude and unconsidered way steps on your toes, it is perfectly acceptable that you snap back with some attitude.

But, if some unaware person does the same in a manner that shows no intention of being rude or obnoxious, in a civilized - or even semi-civilized - society, you have all obligation of - courteously - asking him/her to step aside and let you work.

It is that simple.

If you live in a world where everybody is all the time at each others throats, with no place for mistakes and mishaps, I am sorry for you.
