if someone gives me a gift and I don't have something to give them back, I always feel like a giant d-bag.
hasn't been an issue in a long time now that my circle of friends/associates is smaller and my we've settled into a pattern of not giving each other gifts (we all just go out to a really nice meal together instead), but back when it was (mostly college and when I used to work with females), I'd always buy a couple gifts that I knew I could give to people but could also keep and use myself if they didn't get given out, and I'd bake a couple tins full of cookies to give out as generic gifts.
