Does anyone else find this awkward?

You're walking down a long hallway or corridor at work/school/wherever. Another person is approaching, someone you know, but not very well. You're the only two people walking toward each other. It's awkward to make eye contact from to far away or say hello. I kinda keep looking down till they get closer, than look up and say "oh hi" like I just noticed them. I've seen people take out their cell phones or do something else to look distracted. Does anyone else have weird experiences with this situation or am I the only one?
