Yeah... I was amazed that they seemed happy.
I'd say it's safer to bet that a smart person has more chances of becoming miserable than a mentally challenged one. Because the smarter you are the more you're thinking about stuff and it can lead to loops and constantly comparing thinking what's better, best, while if you're somewhat a low IQ person, you tend to think less and, well, feel more. Mentally challenged people pretty much mostly know they are mentally challenged, but they just accept it as a fact and do not look down on themselves - this I respect.
I find both images great, especially the second one, since the first one delivers too little information to understand it properly. To me they are also touching, bot not in a, weeping-crying way, but more in a, this-is-life-too way.
Also, I find pitying disabled people is wrong.
