Grooming, generally a very calm activity, is a really important part of chimpanzee culture. It establishes and strengthens friendships and alliances. Chimps part the hair and pick out any debris or dead skin. They also will groom scabs off of themselves and each other.

Jody (left) and Missy (right) groom Jamie (center, wearing scarf of trolls). This photo was taken shortly after Jamie had been ill for a few days and had been separated briefly from the group (though they could all still see each other). Grooming is very common when chimpanzees are reunited after even a short separation.
