Somebody Explain Please

Ok, so I am not sure if things like this are allowed, and I will be willing to take it down if it isn't, but here it is: (mind the spelling errors, I wrote this on an IPad Mini!)


What I told was 100% the truth, if you don't believe me, fine I am not asking you to believe me, I am just asking if anybody has a reasonable answer.
EDIT: One (maybe) important thing that I left out: I had been following my friend for quite a while at that point, never loosing sight of him. If that helps...

Short Version: I was at my friend's house, and I had been following him for a while now, with my sister close behind since she had nobody else to play with, I hadn't lost eyesight of him for quite a bit. I got bored, and suggested that we watch YouTube, he went to get his IPad, and my sister and I saw him go up the stairs, we also saw him turn the corner into the hallway at the top of the stairs. My sister and I go into his room, and see/hear him come up the stairs behind us, and walk into his room. Now, the stairway, and hallway, were both much to narrow for him to slip by without us noticing, and we would have seen him come out of one of the rooms to go back downstairs. He claims that he went up the stairs after us, and when we saw him go upstairs, he actually went into the room at the base of the stairs, which we did not see.

 

Maybe he’s a g h o s t......

In all seriousness, I have to look it over again.
