Task: Question Answering
Input (English): In the morning, I texted my friend and asked if she wanted to come to the sauna with me. She had expressed interest earlier so I thought she'd want to go. We decided to take Ubers from our houses and meet there. When we got there, we realized that neither of us had brought a towel. Luckily, they had towels at the sauna available for a small fee. We each paid for our visit and included a towel in the purchase. Then we entered the sauna. It was very warm and humid, just like we expected. It was very relaxing. We talked a little bit but mostly we just sat in silence and enjoyed the atmosphere. It was a wooden structure that felt very rustic. Eventually we started to get overheated, and my friend suggested we leave. We got up and exited the sauna. We thanked the workers at the front desk for our visit and then we went on with our day.
Output (English): Why did they go to the sauna?
