I suppose the best thing to do is to free yourself from negativity. Remove them as a negative influence on your life. You are forever going to meet spiteful, unfriendly people, whether it's in school or out in the big bad world, but it's just learning how to cope with these things in life which I think all comes with life experience and a positive frame of mind! Sometimes I feel intimidated by older people but when I take a step back I realise I am in fact eighteen years old, I know what I want and I know what I need to do to get there. I have managed to survive eighteen years without you and your attitude and I plan on surviving many more the same way. It's your life, you can live it as positively or negatively as you want, nobody else can stop you.
I know I have taken rant of the week to new extremes this week, but after a long and slightly stressful week I think it needed to be said. Its nice to be nice, simples :)
