Tell him to leave. NOW!

"You need to leave. Now." You put your hands on your hips impatiently and he looks a little wounded by your hostility. He raises his hands as if to calm you. "Let me explain." He still looks as if he wants something from you, something you wouldn't give to any stranger. He speaks as you hear his explanation. "My name is Roark. You knew me.. once. When we were children. Your mother would bring you here in the Summer and we would play. Don't you remember hide-and-seek in these woods?" A memory does play out in your mind and weirdly enough. It does make sense. Though, you thought the little boy you played with was imaginery as you got older. You must have made him up! He was an elf, for fuck's sake! "Roary?" The name pops out of your mouth before you can really think about it and his eyes sparkle, his mouth draws back up into a smile. You take a step back. "Roary wasn't real. I have to go." You dart back into the house and lock the doors, checking them twice. Either you are crazy or some weirdo out in the woods knows way too much about you and even donned a very convincing costume to prove it.
