You work on projects together, pass on your morning run, pass in the elevators, or sit just close enough that you can hear their amazing personality come out in conversations with other people their with. The truth is that you’re crushing hard and you have to figure out how to show it. Lots of companies frown on office relationship, so be sure of your office policy and be subtle if you’re risking your and his or her job. Otherwise, we like the idea of giving them something small, not too romantic, or a friendly invitation to do something. A new plant for their desk or a desk accessory is subtle but shows effort. A pair of beer mugs with an IOU for filling them up slipped inside. A running accessory that you swear by and know they’ll love, too. The key is to not make them feel like you’re chasing them down. If you miss Valentine’s Day, these ideas work just as well any day of the year, so don’t give up. Find a good moment and make it happen!
