This is VERY strange!Please help!?

hi,my friends little brother woke up his mom this morning and said"mommy we have to let wendy out of the gate!shes locked in!".his mom just told him to go back to sleep.he wouldnt and he kept repeating the same thing as before.(they live in front of a covent[sp?] and its gated in)so his mom looked out the window and didnt see anyone standing around the gated area,and besides,she already thought that the gate didnt have a lock anyways.so the day went on and he kept annoying her about it and so she finally went out after the non-stop of a 3 year old saying"mommy we have to let wendy out!"so she went out and it turns out that there WAS a lock on the door.and before they went outside,jacob,the little boy,told his mom that there where numbers on the lock and he knew the combonation to it.my friends mom got weirded out and asked jacob who wendy was and he just said"that lady".so my friends mom asked the people around the nieghborhood about it and they said way before the 1970's[cont.]
