Please don't leave laptops, phones, purses, textbooks, backpacks, wallets, etc. unattended in the library.
That's right---anything that you care about keeping: Keep it with you. It doesn't matter if you are going to be back "in a minute", or even "in a jif". That is all it takes for someone to be tempted.
Then you may be left to wonder, is someone using my laptop? or did they sell it? did they sell my textbook? or are they using a different color highlighter in it right now?
