Situation 24.

You have been standing in a queue, patiently, along with several other people, when an old lady elbows her away in front of you...

What would you do?

If she did it intentionally, at first, I would be angry, because I’ve been waiting and the old lady could do the same too, maybe I would tell her: -Excuse me ma'am everyone here is hurry but that's not a reason to be rude, can you wait a few minutes to your turn?... but if I saw that the lady is too old and she didn't do it intentionally, or if she looked sick or very tired I wouldn't tell her a word and I wouldn't do anything to make her see her 'mistake', because in that sense is understandable that the lady wanted to be first in the queue; however I think that no matter the age or gender, we have rules that govern us and we have to follow it if we want an harmonic society where everyone respects everyone.

About what was wrong...

I think that the main problems in my first answer were caused because i was confused and i didn't use the past perfect (e.g. if i had done) when i had to use it and  the same thing happened with the conditional perfect (e.g. if i would have done); but also i think that i can make it better if i read more and i practice with using the past perfect and conditional perfect i will make less mistakes.
