I approve of hugs in general, and a symbolic present (i.e. of no monetary value) would be timely as well as nice. :)

I'm an extroverted programmer: the kind who looks at your shoes while speaking. (OK, the serious answer: I don't know and not sure how meaningful that term is. I am a relatively private person who doesn't crave company, but I'm also comfortable doing things like speaking in public. I used to be more outgoing than I am in my present state.)
