Has there ever been a time where you lost contact with a co-worker? Maybe they left work and you didn't end up getting their number or email to contact further, or you were fired and couldn't speak with any of your co-workers after. I have worked with people I highly respected and never continued our friendship after work. For example, I met some really great people at the call center I worked, but after that job, I never spoke to them again, and it was the same for me. Anyway, I met some great people, and I wish I had gotten their info before leaving.
