Cover art for Hospitality lyrics by Funeral for a Friend

'I fail to swallow my tongue'

I think at the start of the song he wants to die, rather than be in what ever state he is in now, yet he can't pull it off.

And towards the end of the song he realises he has possibly more to live for, and is asking for forgivenessm or something.
