I have read a story in Japanese about a taxi driver. It happened that one night he was near the cemetery in Aoyama and he met a young girl, alone. He picked her up and he brought her home. When they arrived she said that she had forgotten her wallet inside her house. She promised the driver to take the wallet and to come back to pay him. Then the story goes on with these two sentences:
In the first sentence I don't understand how to translate どれだけ in English. In the second one I don't understand why the author put the word 年配 there. I don't understand the meaning of the sentence so I can't translate it.
Thank you in advance for your help!
