you're a immortal. You've decided to take a nap in a coffin for a thousand years. But when 500 years pass your hear a knock, Scratch, another Knock. It wakes you up, but annoyed and confused you try to ignore it.

After a while it seemed to stop... Only for your coffin to be opened. You saw the starry sky. And then a teenager boy, no, two curious teenager boys looking at you in pure shock.

Please state your immortal being, such as immortal human, vampire, demon or anything else..
