i love that their personalities are so expressed in this picture that i can guess what was being said:
daddy: hey, lets climb in the big hole and i'll take your picture.
ella: umm... i don't think that's a good idea. it doesn't look very safe. daddy, i'm scared. i don't really want to...
daddy: daddy's got you. it will be fine.
ella: well, be careful.
bennett: WOO-HOO!!! i climb in the hole!
