I'm not sure if HE knew. A lot of people (who aren't as well informed as us!) think just because something has tags means it's real...but my friend, I should have added, buys knock-off stuff all the time, insisting you can't tell the difference (you can). It's one thing to buy yourself knock-off items, but to give them as gifts is just plain rude IMO. He probably knows they are fake, though I don't know. She knows they're fake, but insists they look real...I do not approve! Her boyfriend has a good job, etc. They've been having problems lately and she's always complaining how thoughtless he is. This just heightens my negative opinions of him. 'Here honey, here's some knock-off earrings to show you how much I don't care!' She, on the other hand, is thrilled. I suppose if she's happy, I'm happy.
