I know baby balls can become comfortable with human contact, and eventually "like" it to a degree. But my allegedly 2 year old BP from Craigslist I got about a month ago does nothing but try to burrow in my clothes. He'll try to run off and find somewhere dark, but if there isn't anywhere, he tries to burrow in me (not head shy at all!). Eventually he seems to give up and just chill.

Over time, will he grow accustomed to handling? I don't think his previous owner did much of it.
