Once you find a favorite finger, go with it

Mom wrote on the back:

At Johnson's Lake, Mobile. The DuBose boys from across the street (Edington Drive), the Everrett girls, Terry Oshita & Cathy & Mark

I figure one of the Dubose boys is far left in the water and one is kneeling at poolside. The Everrett girls must be 2nd from left in the water and far right. Terry Oshita is in the middle in the water. Cathy is 2nd from right in the water. Mark is standing up.

This is from June 1953, and the gathering may be on the occasion of Mark's second birthday.

This picture is the fifth out of ten pictures that came back from the developer in a spiral bound booklet. For pictures, some people have preferred light, favorite clothes, or a a good side, but in this picture and this earlier picture in the same collection, you can see that Mark has a favorite finger.
