I giggled to myself when I saw your thread title, as I knew it would be this.
DS2 is a super fan of automatic doors. He loves them, loves trying to close them, loves the fact they open by themselves, can't get enough of them! When we are in a shop and he darts off, I know exactly where to find him. It is very annoying though as it can be hard to get him away from them and he has broken a few when he uses his brute strength to close them.
DS2 is really bad when we are on the metro (like the London Underground). You have to press a button to open the doors, and if anyone is there before he is he has a meltdown. Usually I make sure we are near the doors, but can't always do this if it is busy.
Likewise I laughed when I read the title as I knew what you were going to say lol!
Yep my DS also loves automatic doors! He stands guard by them waiting for 'victims' to open the door for. They think its lovely and always say 'thank you' to him with a lovely smile which of course makes him want to do it all the more . Not so lovely is when, as you say, someone beats him to the button and then all hell breaks loose. Same goes for someone pushing the button on pedestrian crossings before him too
Gotta laugh haven't you that they are so easily pleased!!
One of the happiest two hours of DS life was on a train where the disabled spot was beside automatic doors...I wish i could find the train that has that carriage. there are school hols where i would happliy ride the rails to nowhere while he sat beside those lovely entertaining doors and they did all the work
