Pretty much everyone in the Teen Club is a teen (hence the name :P) but, as a teen, what is it that annoys you most about other age groups?
Random pet hates, parental rants... anything goes here, I guess.
Let the random hatred begin

Tailgaters

I am a mid-late teen now, I was barely a teen when I joinet.

I hate the I'm better than you ness of the older generation.

People who push you out of the way in a supermarket, just to grab a packet of chips from the shelf

When young kids are terrified of you and make it obvious by staring at you constantly

When younger kids call you ma'am even though you're only in your early twenties (not a teen but was a short time ago)

When people who are just teens or not quite yet thinking they're hard and not respecting them older than them by swearing because they know they can get away with it

On my course there's mature students; one of which has kids a year or two younger than the rest of us, and she thinks that being older than the rest of us makes her so much better and knowledgeable than us. I can kind of understand it because she's been around longer than us and seen more of life, but she really doesn't know anymore than the rest of us do, she just has an irritating sense of self-importance fueled by the fact that she's older than us, even though we're all in the same year group/class so she is no more important or knowledgeable than the people she is older than. Her self-importance and age snobbery can be quite amusing sometimes though.

It annoys me when people use that annoying "well hello there, small child" voice with me. I'm thirteen and kind of short so it happens to me a lot. I also hate it when I walk into a store and all the salespeople rush over to me. "Can I help you, little girl? Where are your parents?" I mean, I just want to buy some soap and I have all these twenty-somethings crowding around me with annoying fake smiles that they don't use for any of the other customers. SO ANNOYING!

Wow, I used the word "annoying" a lot during that paragraph. On a side note, my twin brother is one minute older than me and thinks that gives him an excuse to boss me around. It's not really a problem with other age groups, bit it's still worth mentioning.

If exams were personified: they'd be the worst kinda person.

Got one tomorrow

When people point out every mistake that you make

when you have to go to school 2days a week on summer because your going to go to university after 3 years (and it's got an entrance exam)
(our studding system is way too different from UK and US)

and when you've grown your hair so long for about 6 years and you have to cut it

Did you seriously just revive this thread to make an off-topic post?

When TS3 crashes. And the mood swings that come with puberty.

Allergies

When origin decides to throw an update my way, and my internet is hopelessly slow
