My boyfriend has been very distant and stressed out recently and I really want to give him a nice surprise when he returns back to uni. We're not the type to usually romance or surprise each other (except once when he picked me up from the airport with some fresh flowers!) so I don't want the surprise to be extremely over the top but enough to cheer him up and remind him that I'm there for him if he needs me. What kinds of things have you ladies done for your men when they've been down in the dumps?

More info: we're both 23 and live separately, each with flatmates.
