what has happened to common courtesy?

I swear, people need to find their manners....

When I see an elderly person, disabled or a mom with a stroller....I always help with the door (even if I have to go out of my way to do so)

But, almost every time I am out with my son....I find that almost no one will help me. Today, at chapters I was struggling with the door and stroller on my way in, and a man came up and held it for me as Iwalked through, and then he got the inside door as well...I thanked him and continued my way through the store......

When I was leaving, there was no one around and I struggled with the first door....and when I had a hard time with the 2nd door, there was a woman waiting to enter the store giving me a dirty look....I struggle some more, and the woman finally comes to help me....but I blocked her way because I was so annoyed....

What was so hard about coming over right away......instead of standing there until I am practically outside anyways......

Sorry for the vent, it just really irks me when people do that........
