impatience.

i was stalking someone online today and part of their about me had two categories, one being likes and one being dislikes. i was reading their likes and dislikes and all of them were pretty cliche, and then i came across a dislike that made me stop: impatient people.
now, i don't know this person personally, but it seemed like this was a very attractive male, who seemed to be well liked, and judging from his clothing and phone which were in many of his pictures there didn't seem like there was very much he had to be patient for.
he was about, oh 17, and i dislike people who can't wait a couple days for something they're going to get eventually either, but i wouldn't say that when i think of people i dislike, impatient ones are at the top of my list. what has this 17 year old had to wait for that has made him resent all those who cannot contain their nerves long enough to be patient?
and if let's say one person had to wait one year for something, like idk an inheritance, and another had to wait 15 years, can the first person honestly blame the second for wanting the money? Where is the line that views impatience as understandable?
i'm not quite sure if this is a fit of bitterness about some cute boy who i might be jealous of and not know it and so i'm subconciously(sp?) mad at him or if this is a fit of interest that wants to delve deeper into the mind of a teenager i know nothing about.
either way it's far past my bedtime and I can't sleep. this is most certainly a problem.
