You're just able to ignore what you don't like is my guess. Like you say, wallpaper. I believe you, really.
I can't do that. The negatives become an irritant to me, even when I don't engage with them directly. Just being in proximity bothers me and I do notice it as I pass by and I feel the energy from it and it's draining.
Kind of like guy from India watch sellers, some guys just tune them out completely, other guys naturally respond on some level and it irritates them, other guys actually like the dudes and buy a watch. I think you are the former type of guy.
A good lesson for people considering Pattaya, know thyself!
