"The giraffe challenge" on facebook?

[Dave]

My friend posted this on facebook:

I have had to change my profile picture to a giraffe. I tried to answer a riddle and got it wrong! Try the giraffe challenge!! The deal is I give you a riddle, you get it right, you get to keep your profile picture, get it wrong and you change your profile picture to a giraffe for the next 3 days!!!

MESSAGE ME ONLY SO YOU DON'T GIVE OUT THE ANSWER!!!

Here is the riddle: it's 3am, the doorbell rings and you wake up. Unexpected visitors!! It's your parents and they are here for breakfast. You have strawberry jam, honey, wine, bread and cheese.

What is the first thing you open? Remember, only message me the answer - if you get it right I'll post your name here, if not, I'll message you and you'll have to change your profile picture!

And her profile pic was a giraffe. So I messages her : "the door" ( which I'm pretty sure is the right answer) and she said : "go change youur profile pic (my name)." Notice that there is two U's in "your". It does that when your account gets hacked and it's spammed in comments and stuff. So then I said: what's the real answer then? Then she said: Lol you'll see . Then I said: I'm not changing my profile pic. Then she said: "PARTY POOPER !" Then she wouldn't answer me after that. What creeped me out was that it took about 30 -60 seconds for her to see/respond, AND it said that she wasn't even on since two hours ago. So I guess her account got hacked or something. Now I think i might get hacked. Anyone know what this is? Answers greatly appreciated.
I don't care about the answer to the riddle. I wanna know if my friend was getting hacked, because it said she wasn't on, yet she was messaging me.
