My cousins copy me!!! What should I do

Anonymous
ok so I have 2 cousins from my aunt ( a girl 17, a boy 15), I know younger siblings and cousins do copy older siblings and cousins whom they look upto, but that should be done in a good way, its good to be looked up to but it gets really annoying at times. the girl's problem is not only does she copy but she then has an attitude about it for e.g I was going out and made a cute hair bun with nice clips and she saw me and said " I can also do this infact I can rock this look better" like what the! I ignored her, she has a habit of doing everything I do and tries to prove she's better at it. The boy acts all cool and disses things and says that's so lame but when I do it all of a sudden its cool, for e.g songs, then he would go download them and say yea I always thought that song or TV show was cool, I'm obsessed with Redfoo and I even got his party rock frames, my cousin said he's so lame and now 2 weeks later he's learning how to shuffle and bought himself party rock frames too, its not that bad to be copied but I hate it when they think its lame at first try to diss it but after seeing I don't give 2 hoots about what they think, they copy it, make it seem as if its cooler on them and then say "we always thought it was cool". I'm a girl but I'm tall (6 ft) and they are always like we are going to be as tall as you, well the girl remained average heighted so she stopped saying that but the boy is still obsessed that he wants to be taller than me, I mean geez guys are usually taller than girls so even if he is gonna be taller so what? The girl after seeing my friends and other cousins commenting on my fb pics that I looked cute and nice got jealous and she then messaged my friend on fb that don't be fooled by her pix its just makeup, I got so pissed like who the hell are you to message my friends on fb and talk trash about me and I deleted and blocked her, ugh I'm sick of these 2 demons, they live in another city but they come twice a year. The girl always says she wishes my dad was her dad too ( her dads a bit messed up) How can I avoid them, they are going to be around for life because they are my first cousins (my moms sister's kids).

and please no trollish answers
