Cover art for Seagull lyrics by Shout Out Louds

At the beginning, he doesn't trust his friend so he sabotages his friend in some way. Then, he realizes that he is just as bad as his friend was, and his friend had no reason to trust him.

Why do you think it's called seagull though? I met the band awhile back; I didn't think to ask.
