Depends on how much. A small lock of hair I have always thought of as a sentimental keepsake. But I am no expert on these things. Does that make me ghoulish?
No. Doesn’t anyone read literature? Carrying a lock of of hair of one’s beloved has been done since, well, at least since people have been around I’d say. I have a lock of hair from my son’s first haircut and he’s 31. I also have one of his baby teeth.
