Be real

Don't try to be someone you're not, or you may get typecast in a narrow role that doesn't include all that you are. If you're normally casual and dress to the nines whenever you meet him, he may reasonably expect you to dress like that all the time and be disappointed once you're together. If you pretend you don't like books and hook up with him, you may wind up spending the rest of your life having an argument every time you want to order from Amazon.
