This is good advice (less so, however, if you're concerned about turning off NTs in the process).
I thought I'd answer the question, but then I thought that I could not extrapolate my own experiences and proclivities to other Aspergian females, so I went with a different approach:
Where to meet and and how to spot an elusive Kaybee:
-A bookstore. She's the one who went alone and has a gigantic stack of books, which she handles lovingly. The books are probably not typical fare: Books on languages, history, social sciences; books which are considered classics or which are obscure; comic books.
-The supermarket. She's the one who is there alone with a basket full of healthy food and, sometimes, alcohol. She is avoiding getting too close to or looking at the other patrons.
-A quiet, scenic spot in town, such as a park. She is alone and is either walking/riding her bike quietly or sitting with a book. She may be visibly distracted by local fauna, watching insects and other animals rather than humans.
-A social gathering of a mutual acquaintance, especially a variety which involves games (video games, board games, card games). She'll be easily spotted in such a gathering because she will be the one who's female.
-Here. She is the one called "Kaybee" who carries a foxy image with her wherever she goes.
If you speak to her, she is likely to be startled. Approach with caution and don't make any large sudden sounds or movements. Don't touch her--she might take this as an act of aggression. Have something to say--empty greetings will only make her cagey, but she can be quite receptive to words with substance and/or humor.
