As many on this forum will know, one major tutoring website tells you when someone has viewed your profile, and gives you a good idea of where they live. The other day, someone looking for A-level physics tuition viewed mine. They live only 5 to 10 minutes walk from me, yet this wasn't followed by an enquiry, and a further message from the website showed that they are still looking. I would place a hefty bet that the reason they didn't contact me is that they were too lazy to spend just a few minutes walking to me. When I think of how much effort some students put into coming to me it's hard not to hope that the lazy students get the grades they richly deserve.
