I just spent the last 2-3 weeks putting together a data set for a paper with a former student. Ten minutes ago, I sent it off to him. Now it's his problem for a while.
That's the nice thing about working with coauthors - you get to hand work off.
Of course, all this means is that I get to work on another project while I wait for this one to come back. I have several that coauthors have handed off to me. So, it all works out, I guess.
Enough bloggery - back to work.
