I don't get it...

I honestly don't understand it. Every time that I am in a rush it seems like everyone around me is slow as hell!! But then, every time that I want to take my time everyone around me is in a hurry! Sometimes I think that it is my imagination, but then other times..I am like..no honestly...these people are doing this to piss me off. For instance, say you are on your way to work and you are running late....you will most definitely be placed behind the slowest dumbass on the road..or placed directly behind a school bus who stops at like every house on your route and then stops one house before your turn off for like ever! Finally after like 5 minutes of sitting behind this stop sign...a little boy runs out of the house hand-in-hand with his mother and she places him in the bus, kisses him a million times, checks his book bag for his hw and finally places him on the bus. Or...you are going to work and you are like 5 minutes early so you stop at Dunkin Donuts to get a coffee. You hop into the drive through and you are placed behind a van of a million people who are each ordering a uniquely made coffee and specialty ordered breakfast sandwich. You are now stuck behind this van and unable to get out of line and you are now..LATE for work...Honestly, I just don't get it!! And for some odd reason you feel that yelling at these people/cars from the inside of your car will help move this situation along. What is the person infront of you thinking? I mean.. why can they take their time? I mean....don't they have to be somewhere too? Don't they CARE aout me?!!! But then again..someday..I will be that person that is holding up the line or who is the recipient of some intense road rage.....
