Yeah, it happens. I feel your emotion. #36 is so easy I didn't even care to check my answer. Suffice to say, I blundered badly. Looking at the answer I was like "huh?!" and after rereading the brain game it hit me. It kinda feels like a child-proof object that I cannot seem to master (and that happens way too often). Or worse, switching on my washing machine. It has touch buttons that simply fail to notice my attempts. My son of one and a half, always helpful, assists me in getting life into that 'thing'. And then I am humbly subjected to the brutal truth of life: IQ is just a number. On the bright side, there is something new to learn every day.
