You can normally tell the difference between the clients who want to talk and the ones who only reply out of politeness. The ones who don't want to talk, if your doing something like foils or a colour, ask them if they want a magazine, that way they get their quiet time and you don't feel uncomfortable that they may be bored.
I like my old lady's, it leaves you a bit sad, but really happy at te same time that your the only person they usually see, but it's nice that your in effect their best friend. I always make mine feel like a young girl by being slightly cheeky and asking if they have been to the "disco" on the weekend.
They also love to tell you storys or explain what the local area was like before u were born.
Start with how've you been, then onto been up to much since I last seen you, and finally what you doin this week. Xoxo
