ok so i saw this on facebook, and simply had to repost, it's just too good. i really laughed out loud multiple times.
Since this picture is so funny, there needs to be a group dedicated to it. I am pretty sure its the boy's fish.
I ask myself, "Why would that girl have a fish?"...I don't think she would.
She probably doesn't even know how to catch a fish.
Most likely the boy caught the fish and the girl took it.
Maybe it was dead, and the boy found it on the ground.
Either way is possible, and either way it happened, I'm almost positive it's not the girl's fish.
