WILT
Probably some type of self comforting or attachment technique. My step son used to twist his mom's hair in his hand as he was feeding at breast, and he still likes to touch peoples hair. Perhaps her ear lobes were played with in a soothing fashion when she was younger and she sees this as an expression of affection. Either that or she's watched a lot of Carol Burnett reruns. Your guess.
