Kurri, I am the cousin who shares nothing with my other cousins - any special occassion, event in my life is kept to myself and my immediately family strictly. I know eventually they'll find out but I hope when they do, they'll realise that I chose not to tell them, thus, I want them a certain degree away from me and my life. So there, I am that evil cousin.
I wasn't always like this - but excessive nosiness and lame comments about everything that makes me happier kind of turned me off of 'sharing goodnews' with extended family.
Thats the thing though, youre not the evil cousin because you dont tell anyone, they however tell EVERYBODY, EXCEPT my family. Every other realtive, all of our cousins, second cousins, aunts, uncles even family friends are informed before us. Thats whats upsetting, the fact that is deliberately kept a secret from just us.
