Sure! Here's a possible letter in English about weekends and holidays, addressing all three questions, within 80-90 words:
Dear Friend,
I usually spend my weekends relaxing and hanging out with my family and friends. On Saturdays, I often go to the park or watch movies. Sometimes, I stay at home alone, especially when I need some quiet time. Next weekend, I plan to visit my grandparents and go for a bike ride. I look forward to a fun and restful break. Weekends are a great way to recharge for the upcoming week!
Best regards,
[Your Name]
