L and Light

It was raining heavily. Light went up to the roof and saw L. He was standing in the rain, hands shoved in his pockets. Light stepped closer so that he would be noticed and asked:
Light: What are you doing here?
L turned his head slightly toward Light.
L: Just this. Listening to the ringing of the bells. Do you hear them?
Light listened closely, but nothing could be heard except the sound of the rain. They stood like that for another 5 minutes. L asks Light if he has ever told the truth, to which he receives an evasive answer. Soon, Light said:
Light: Let's get out of here. You're soaked.
L: Yes, perhaps.

After that, they were on the roof of the task force headquarters (the Pacific Bank building in Tokyo). Light was sitting on the steps, drying his hair with a towel. L stood behind him, sighing.
L: You could at least wring yourself out...
Light: This is your fault. You dragged me out in this weather.
L: Sorry. I regret it.
Light didn't answer. Suddenly, L stepped closer and sat down in front of Light.
