Cover art for Your Father lyrics by Radio Dept., The

In the first verse, the fire represents internal lust and passion for each other, kids growing up with each other and feeling that for one another. The dad caught a few cute moments of them with one another in a slightly romantic or something manner, obviously to show to someone, perhaps to the other persons' parents. Then they may have done something like kiss or something, and someone came in with water, they were so embarrassed they wanted to expire, or die :).

Second verse, obviously theyre growing up and now older, we were first kids when we met, but now were not, and theyre probably getting more intimate, but the father doesn't approve because thats how fathers can be sometimes.

Third verse, obviously they grew up and lost each other, drifted apart or something, or in context, the father probably pushed them apart from each other, and she just learned to live without him and found someone else. But it doesn't sound like he transitioned so easily. :)

Such a great song :)
