Shopping

I went to a nearby shopping mall today.

I wanted to buy climbing shoes, but I couldn't find good ones.

On my way home, I found an outdoor shop and entered it.

A saleswoman talked to me.

She was very nice, and knew about their product very well (you can also say "very knowledgeable")

よかったですね！ハイキングとか好きですか？

英語で書くとき、最初過去形で書き始めたらずっと過去形を使った方がいいです。それで「can」を「could」に、「feel」も「felt」に変えました。

これからも頑張ってください！
