Someone likes Avril...
'Somebody else, 'Roundeveryone else' - The person who the song is talking about, 'becomes somebody else' when around other people. 'Roundeveryone' should be 'Around everyone else' but it has been condensed to fit the style of the song. This follows on from the previous paragraph, if you were to write it normally it is easier to understand.
...But you become somebody else, roundeveryone else...'
Honesty Promise me (Why is "p" capitalised) - I don't know why P is capitalised here, I have had a look on other websites that have song lyrics on and most don't capitalise the word 'promise'.
