I am fucking with my người yêu

My school is very beautifut . My school has about 200 students.My school is full of facilities

I live in the suburbs of Nha Trang city. There are many good things about living in my neighbourhood. First, it has beautiful parks, sandy beaches, and sunny weather all year. So, it's very good for outdoor activities and events. Second, the traffic here is also great because the roads are wide and people follow the traffic lights very well. Also, my neighbours are incredibly friendly and helpful. You can make friends with them and ask them for help easily. However, there is one thing I don't about living here. It's quite inconvenient because if you want to hear some live music or watch a movie at the cinema, you have to catch a bus to the city centre. Despite that, I still love living here.

rất tiếc
