I feel stupid for a post on fb?

So I haven't talked to this girl in a couple of weeks but on fb she posted a picture of her standing next to a ferarri. I commented asking her if she owned it and now I think she blocked me from seeing the picture which means she probably deleted my comment. Wth? She keeps posting other pictures of her and the car so what was her problem? I feel so dumb right now because I usually wouldn't ask stuff like that but my friend wanted to know about it. I want to completely avoid her now...what would you do if you were me?
Another comment said it was her parent's so I don't know it could have been some privacy issues and we're definitely still friends on fb. Should I inbox an apology saying I didn't mean to say that?
