Especially when you're not used to it. What I tend to do to double check cerry-picks is git show both commits, and compare the entire diff line-by-line to make sure I didn't misplace anything. Another trick is to use the raw patch instead of cherry-pick, since that won't do a 3 way merge where you might get confused with other context and fun stuff like that.
