Had a buddy whose old HP 731 plotter just stopped one day in the middle of plotting a subdivision plat. Thing literally started sparking and he had to unplug it from the wall. He said he left it sitting in the corner of his office for like two months before he could bring himself to haul it out. That machine had survived three office moves and a coffee spill that should have killed it years earlier.

And yeah I get what thomasm41 is saying about it not being that deep, but I think it can be both things at once. Like yeah it's just hair and it grows back, but for a lot of people their natural texture is tied to how they see themselves and their family history. The friend coming in and saying she's erasing her culture might be going a little too far, but there's a real conversation there about why someone wants to change their hair. I'd probably ask the client how she feels about her natural curls first, and if she's just tired of the upkeep versus if she feels pressure to look a certain way. That way you can figure out if it's about convenience or something deeper.
