i like 'outstretched_hand' , though 'take my hand' is nice. a lot of characters have their hand extending to the viewer, but its not done in as a nice gesture.
as for proferred. its a bit complicated, and its certainly something i wouldnt think about if i want simple ^_^;;
I'm having trouble imagining a character reaching for the viewer in a non-friendly way without it being tagged as "reach" or not being tagged at all...
