I love my weekends
Winter
Winter is a time for cozy family dinners. People spend their weekends doing memorable things with their loved ones. My tradition during winter weekends includes visiting my grandparents where my entire family unites. Moreover, winter is associated with the Christmas holidays. So I put on my favorite socks and a woolen sweater and play some relaxing songs of the season. The opportunity for holidays often lights up the desire to travel. My family enjoys the snowy areas and activities such as skiing and skating. Overall, winter is the right time to try something new.
Spring
Spring weekends are the loveliest and most pleasant days. The beauty of nature in that season inspires me to be creative. I have been obsessed with photography for quite a while already, so I spend most of my spring weekends outside enjoying the weather and taking pictures of the prettiest places in our countryside. Also, unlike the winter, spring is a great opportunity to experiment with clothes, because I do not have to wear heavy coats, but at the same time, I can try some new and classy outfits.
Summer
Because of the relatively high temperatures during June and July, I do not like to be outdoors. I used to spend my holidays at home, but I got bored. I realized that there are a lot of activities that might keep me interested and busy during the holidays. Just recently I've signed up for art classes and joined a sports club. Summer became my own time to improve myself and be a better person. When I hang out with my friends, light clothing is a must for me. During summer I appreciate every minute of my vacation and try to spend the time usefully. Summer vacation means lot of fun.
Autumn
To me, autumn weekends are rather sad, as the schools reopen. It is the laziest season of the year for me. I use the time to think about my future and plan for it. Sometimes, I spend autumn weekends sleeping late, watching TV and playing computer games. I do not go out much during this time. I prefer staying at home, so I wear cozy clothes, being comfortable in every way. Being indoors, I do my domestic chores and mind my clothing and emotional wellbeing. Thankfully, fall weekends never last long.
1.One of activities that my family enjoys in winter is skiing.
2.Spring is the right time for me to try on different types of clothes.
3.I wear light clothes when I am away from my friends in the summer.
