This part stood out for me. Don't you have this problem when making small talk with
anyone? Why is it different with hairdressers? Many times I have remained silent instead of saying something that comes into my head because I think "they've heard that a million time already I bet" or "that's what everyone would say" or "I bet they are sick of being asked that". It's not a hairdresser problem for me, it's a people problem.
The solution is to just say the lame, boring things that everyone else would say. Everyone else would say it, so it must be okay to say. Rarely do I follow this advice though because I feel ridiculous doing it.
