Aliens are the people who tell us that we're ugly. That we're fat and annoying. We call them aliens because we try not to believe in them, thinking that their not real but in the back of our minds, we know that everything about them may be true and in this case, its their words.
Aliens want to hurt us, bring our self esteem down and try to drown us in our own pity parties just because we're vulnerable. We're human.
The thing is, when you think about it;
We're aliens too.
