Unless of course you actually take an interest in them as individuals and use the time to find out what they enjoy about your subject and what they hate!
When I first met my middle set of Year 10s on Friday morning I needed to do something different and so started off by asking them to write down two things that were true about themselves and two things that were a lie. Or if you prefer: fact or fiction?
A good idea? Well... You'd think until one of my students pointed out that the three examples I'd put on the board about myself (to demonstrate what I meant) where all actually true.
Damn it I thought to myself as I quietly joked with said student. How on earth did they guess their teacher was a former journalist, is pregnant and allergic to melon?!
Anyhow like a consummate professional I carried on and actually thought it was quite an enlightening exercise. I found out that one had visited Brazil six times in the same year, another can only read off yellow paper and judging by the smile on each of their faces - all appreciated the fact that I had actually taken the time and effort to find out about them.
