They are good listeners, know how to summarize everything in 1-2 good words. Can be very sweet with gestures when they really like you it surprises you.
Possibly the biggest problem i have with them is that they sit back and wait for me to entertain them most of the time. I could go on and on and on and on and get an *ok*. I would do crazy things to grab his attention and it barely moved him 2 cm.
You need to keep working on them communicating, their ideas aren't readily shared, and even more for their feelings.
It was a delightful experience though.
