Without questioning his seeming self-imposed isolation, I asked him what he was working on. Silently, he showed me the most amazing thing. A tiny car, perhaps two inches long, with a tiny steering wheel, impossibly tiny foot pedals and working doors with millimeter-sized handles.
I oohed and ahhed and asked him about it. What I did not do was question his choices. There was no way to know for sure what he was thinking without embarrassing him in front of his group. Perhaps he felt that he didn't fit-in as the only boy in his group. Perhaps he was simply bored with the prototyping process. But I could be sure of one thing. What he did not feel was disapproved of.
