I remember all the way back to middle school that I excelled in this subject. It has for so long been one of my best subjects by far. That is history. Memorizing facts was always easy for me. For a lot of other people with aspergers this also holds true.
This doesn't only apply to history.
Last Friday night I ate dinner by a family I know back from Kansas. I was able to remember quite a lot of things about them that I had not been using for the past 2 years. I mentioned a conversation I remember having, and even a class that the husband gave right before he left Kansas City.
It's always important to remember and know your strengths.
