Caveat
If you burn out I won't have the energy to go see you.
I can't be a candle forever, I have my own problems to look after. I've got a weak body made of wax, and when the fire gets too close, I melt. My wick is rather useless, blow and I'll go out, I'm left in darkness. The last time I lost my flame, you came and lit me up all over again... but now, I'm really worried.
I'm worried that you can't keep your own flame. Your own body's getting weaker. I see you getting stumpier. I see the wax dripping down, you're getting short, your own wick's becoming unreliable.
Do you get this?
If this goes on, who's going to light me up when my flame dies out again?
