Sure! Here's a sample letter in English about weekends and holidays, answering the three questions:
Dear Friend,
I hope you're doing well. I wanted to tell you about how I usually spend my weekends and my plans for the upcoming days.
Usually, I spend my weekends relaxing and catching up on things I enjoy. I often go out with my friends, watch movies, or read a good book. Sometimes, I help around the house or do my homework to prepare for the next week. It’s a nice way to unwind after a busy week.
Last weekend, I stayed at home all day. I needed some time to rest and recharge, so I did some cleaning, watched my favorite TV series, and listened to music. It was quite peaceful, and I enjoyed having some time just for myself.
As for next weekend, I’m planning to meet up with my friends for a picnic in the park. We haven't seen each other for a while, so I’m really looking forward to spending time together outdoors and having fun.
That’s a little about my weekends. What about you? I’d love to hear your stories too!
Take care,
[Your Name]
