Picking up...

I really don't like picking up other people's code.  You have to work out what it does, why it does and how it does.  You'll always have a slightly different way of doing things and it's hard to integrate the next steps in.  If something doesn't look right, is it a mistake, is it something that hasn't been gotten to yet.

That said, it was fun filling in some of the blanks and the end of the day did feel like I achieved something which is always a plus.
