Never had this happen before

For past 4 days I was at my place looking for a small pig to shoot with my 22 mag rifle. My wife's family will be here in few days so I wanted to shoot a small pig I could cook whole in my grill. I wanted one that was about 50 lb. or a little less.

I saw about 20 hogs in 4 days but most were too large or too small until this morning. At about 6:45AM I saw a sounder of 4 hogs come down along the edge of palmetto thicket. It was a large sow of about 170 lb. with 3 smaller ones of about 40 lb... perfect size for my purpose. I waited until they were about 50 yards away when they stopped to smell some sour corn I had put on the base of a palmetto palm. All 4 pigs started moving around the palm eating the sour corn and I picked out a brown pig that I was going to shoot. I patiently tracked the pig for about 3 minutes while waiting for him to get in position where I could take a clean brain shot without wounding any of other pigs. Finally he stopped away from other 3 pigs so I shot. At the shot my pig dropped and started the usual leg shake as if it was running but I knew my shot was good and it was dead. At the sound of the shot the sow and 2 little pigs took off immediately but the sow returned within seconds to the dead little pig. She stood there about 5 feet away as if she was waiting for him to get up for about 20 seconds. When the little pig finally stopped moving she stared to run away but then came back again to the little dead pig and stood there for about 10 seconds. Finally she started walking back to where other little pigs ran off to. About a minute later I saw the sow and 2 little ones about 100 yards away walking towards the orange grove.

I have never seen a sow behave like that before. She was waiting there for her little one to get up and run away with her. If I wanted to I could have easily shot her while she stood there. When I went down to retrieve the pig I felt a little guilty.
