My friends say that I am spontaneous, outgoing and warm. Anyway, I don't know if you can believe them, they are my friends, they are not going to say anything bad about me.
From my experience, I learn way more about people by talking with them over coffee, than I do from emailing back and forth. Recognizing not everyone will click, even if it looks good 'on paper'... I'd rather invest some time to meet than to spend a lot of time writing, setting up expectations that may or be not be met.
