Unfortunately, she learned a valuable lesson. Probably, never again will she leave something that expensive in the care of a stranger. Obviously, she should have taken it with her. But, we all make mistakes.
That said, you told her you would watch it. To me it's pretty clear, you should replace it.
I am not so sure of the validity of this story. Your signature is odd, as well as your lol response. Also, you make no mention of either telling your prof or informing security.
Wow... I was reading through this and could not believe that you were the FIRST to address the stupidity of the girl. I get that it sucks to bring everything with you all the time, but WELCOME TO THE REAL WORLD. She learned a valuable lesson while in college, and unfortunately it cost her ALMOST as much as a day of classes.
lol So a girl entrusted you, a complete stranger, to "keep an eye on her iPad?" Did flags not go off in anyone else's head of how stupid this sounds? I do not let my iPad, laptop, phone, keys or wallet out of my site. EVER. iPad is clearly a hot item right now and she left in in a room full of immature, questionably moral, BROKE students? But NEVER FEAR..... She left it in the hands of the OP who sounds like a completely honest, trust-worthy, stand up guy!!!! Cough Cough DOUCHE BAG! Cough Cough I don't even know the OP but just based off of this story, his signature, and his other posts, I would not trust him to watch a pickle, much less my iPad!
OP - This story sounds all too convenient for you after your post about parting with your iPad. If the story is in fact true, then leaving it out of your site was a real douche bag move, but unlike the other posters, I really do not blame you, or think you owe her anything. She trusted an expensive piece of technology to someone she didn't know, and that alone puts the blame on her. She should have thrown it in her bag and carried it with her to the bathroom.
Having said that, I personally think this whole story is BS, and that the OP just writes random posts hoping to get a reaction from people, but that's just my opinion. However, if the OP is not making this up, I think the girl would be smart to try to catch the OP in the act, because it sounds to me like he took it. haha Maybe that is the ipad that he sold and was okay with it! hahahaha Also, if you had an iPad, you know all of the possible ways to track it and would not need to ask.
Sorry for the long post, but must add one more thought. Offering a reward when you KNOW it was stolen from somewhere is USELESS. Like the thief is going to put them in a position where other people would know he stole it. The thief is already long gone with it, and has either kept or sold it. My guess is the offered reward would not be near as much as the actual iPad. (otherwise it would be more simple to just go buy a new one)
Last thought for Rhinosrcool - INDEED! Go Vikings and Twins! Sadly I think Vikings had their chance last year and blew it but I am still pumped for the season. This is however the year for the Twins, and I do not think they will blow it. I see another World Series coming to the great state of Minnesota!
