Aliens are already here. They are called Democrats. They look just like the rest of us, for the most part, but they are devoid of rational thought and true compassion. Many of them are readily visible by the bumper stickers they have on their cars - “Obama Biden” or “Coexist” - for example. Other than that, it is hard to spot them just by looking.
Sheesh. Well, that explains why I have the disturbing feeling my subconscious is being violated by alien probes.
I live in Massachusetts.
