Is this weird? HELP!? need your input on this!?

No, I don't think that's weird whatsoever. A lot of girls at my school did that lots, and it's perfectly normal! I had a purse, like my Burberry Tote Bag, and I would carry my pencil case, makeup bag, body lotion, dictionary, books, calculator and etc in it. It would be the bag I would carry around all day, but at the end of the day, I would put my binders and textbooks in a shoulder bag, and just put it in my car.
