Astro game and lost boy

Monday at school one of my friends offered me 4 Astro's tickets. At first I told her no, because I was tired. We had been gone all weekend playing and working a baseball tournament. I thought about it some more and decided it was stupid to turn down free tickets, especially because Mason had been asking me if we could go. I told the boys they had to really clean their rooms and we would go. They vacuumed dusted and basically became my slaves in order to go to the game. We weren't sure Brad would be able to make it, because he had already planned on working late. He told us he would meet us there if he could. We left pretty early because Mason wanted to try and get autographs. Lucky for us one of the Astro's threw him a ball and then signed his ball and the one Tanner had brought with him. Tanner came running over to me and asked me how much he could sell it on ebay. I asked him who signed it. He didn't know who it was. I'm thinking no one is going to buy the ball of an unknown Astro. We watched the game until about the 7th inning and then the boys played at the Squeeze Play for a while. When we left the play area the boys were thirsty. I didn't feel like taking out a small loan to buy them another drink, so I pointed out a water fountain and told them I was going into the restroom. When I came out I saw Mason watching the game, but didn't see Tanner. I asked Mason where he was, but he didn't know. We checked around, looked in the restroom, Mason walked outside and looked by the squeeze play, but no Tanner. I stood there wondering what to do and getting really scared. I started to walk toward the door to check the Squeeze play area and saw Tanner walking up with a weird looking dude. He had those things you put in your earlobes that stretches them out. It didn't register to me that they were together. I asked Tanner where he had been and they guy said he had found him outside of Minute Maid Park walking down the street. Tanner said he was going to look for us at the car. He didn't know where I was. I thanked the guy for bringing him back and started on my lecture for Tanner. When I got home and told Brad what had happened he said, "You mean Tanner was with a freak." I said, "Yes, he might have looked like a freak, but he had a heart of gold. He brought us our Tanner back." This has freaked me out. I have talked to Tanner about what to do from now on if he is ever lost. I guess I did this to him by telling him we were going to the car when Mason left us in the mall. Poor kid, he must be really confused. Brad yelled at him and asked him what he was thinking. "Don't you know your mom would never leave you?" Of course I wouldn't. The two incidents were totally different, but I guess in the mind of a little boy he doesn't see that. This was not a great day in my parenting life.
