Lyric discussion by AllenC 

Cover art for Bug lyrics by Mandy Moore

Mandy said on Ellen the other day that "Bug" is the nickname Ryan (her husband) gave her, so if it's about him, then I'd say it's about wanting to be with your loved one but you can't because the two of you are always in different places, which makes sense because they're both traveling musicians. And sometimes because of that, questions are left unanswered.
