• learn what the ticket wants, not exactly what it says
• you'll sometimes run into old code that some don't want to delete or mess with. code artifacts!
• in pairing with someone on tickets, you might not understand everything. as long as you understood the gist, you're good.

one thing you can try and do:

• try to reproduce what they did on your end. if you can't remember something exactly the way it happened, ask them!
• look through the db to observe what tables are there and what columns you get. the columns will indicate to you what kinds of things get tracked. beware--some columns aren't really used anymore! the tables will indicate the purpose of the data.
