adapter

Last time I went to my friend’s store and got an adapter, but I didn’t have any cash with me, so I took it away and said I would give it the same when I came next time. Unexpectedly, I forgot it later. Today, when I was still using the adapter, I suddenly remembered that I hadn’t paid for the last time I bought the adapter. So I hurried to my friend’s shop and apologized to him again and again. My friend said nothing was so kind. He also forgot it. To ease the embarrassment, I also bought something else and gave the money I bought the adapter last time, otherwise I wouldn’t accept money from any friends if I knew I’d come here specially to give money.
