This Is The Last Time - "TITLT is indeed a confusing song, which is actually
something i regret, but the meaning is hard to explain quickly and simply.
here's my attempt.

it's mainly about regret. i was thinking about how you can have a huge amount
of affection for someone and yet not have that magic spark that makes you feel
like you're in love. whenever i hear the song i feel it's a snapshot of the
moment of two people saying their goodbyes...i can actually see them stood
facing each other. what a rotten moment that is eh.

anyway so you have a bond with someone but you don't want to stay with them
forever. so you decide to go. but you're not saying 'i hate you and i'm
leaving'...you're trying to say 'i think you're great but i've seen that
there's something more perfect and magical out there for me and i need to find
it. but i will always be your friend if you need me.' does that make sense? so
the bridge ('something i wasn't sure of...etc') is about the sense that there's
something more magical to be found. making that decision to leave something
comfortable to search for something perfect is difficult, so the alternating
lines of the chorus are almost a debate going on in your head...you're saying
'this is the last time we'll share these intimate moments, time will make
things better, and of course you can turn to me whenever you want to, i don't
mind.' if you split the chorus into two parts using alternate lines it makes
sense! i guess the feeling of conflict within yourself and the difficulty of
making that decision is what the song is really about. it's not sarcastic or
anything but it is certainly confusing. sorry!

i like trying to write about confusion and grey areas because life is not
normally very clear-cut and simple, especially when it comes to the way people
interact. hence the album's title. how many songs are there at the moment about
how you're not good enough for me so **** you? the eamonn/frankee nonsense
being an obvious example but look at any number of recent hits. how often is
life really that simple? i guess that's why 'dry your eyes' was such a popular
song...it talks about the confusion and mess of breaking up, and that's a
reality that people recognise." - Tim - messageboard - Source

"This Is The Last Time is a weird one. I feel that it's a very well-intentioned
song, and the idea behind it is good, but I don't feel like I really said what
I wanted to say in a very clear way, basically. The song is about being in a
very comfortable relationship where you feel a lot of affection towards
someone. It's about feeling that's all great and you don't want to hurt this
person, but at the same time you feel like you wanna get out there and find
something that's more kinda magical, and a real passionate love; it's not just
about being cosy and comfortable, it's about finding something that really sort
of makes you feel alive and lights up your life every day. So it's about the
dilemma of having to leave that person behind, and go off in search of
something that's more kinda unknown, and just a romantic idea. But at the same
time it's having to try and say that to the person you're leaving behind, and
how to explain that - obviously it's a difficult thing to do. My kinda view of
things isa little bit ... I tend to always be looking for the more difficult
and confusing things. Whenever I start off writing a song that's kinda quite
happy and positive, I always end up starting to undermine it and writing lyrics
that undermine that, and by the time I've got to the end of the song it's much
more full of doubt." - Tim - Strangers DVD
