Is it bad that I chuckled at this? (Fanny would say it's probably a sign of my lack of social interactions in general)
25% come fairly regularly. They need little effort to make them come.
50% come more than once. They need some help, some assistance but they come more than once.
And the other 25% never come at all. And I mean never. No matter how much you coax them or give then incentives. I often want to ask them how they feel about this but I don't want to put them on the spot. There must be some serious reason why they can't come and I think they need some help there. I'm sure they want to come but they just don't seem able to.
In case yous are wondering where I was, it was a conference on increasing attendance.
