A party is a great occasion to gather friends and relax at the end of the week. When you are immersed in study for the whole week, a good break is what you need. I like going to parties or organizing them at my place. Despite the fact that one needs to thoroughly clean an apartment after parties, I like to invite friends to my house. In addition, you can also clean up with friends after noisy parties. Then the process will not be boring.

Parties can be themed or simple. Themed ones are often timed to coincide with a holiday. For example, Halloween or New Year's parties are the most popular and spectacular. Proms, summer beach parties, etc. are also common. But these parties usually don't have a dress code.

Food, drink, and entertainment are an integral part of any party. An organizer decides for him-/herself how he/she will entertain the guests, what to feed and drink. As a rule, there are snacks, small desserts, or drinks on the tables.

Music is another must-have item for every party. It is the means to support guests of the event and creates the necessary mood. It is impossible to imagine such events without music.

Halloween was the last party I attended. My friend arranged it. I chose the suit of Death. I had a long black cloak and a real scythe. There were about 10 people at the party. We were all originally dressed. A vampire, a resurrected nurse, a zombie were the most popular costumes of the evening. We talked, played board games, and danced. As the night fell, we went for a walk along the streets, scaring passers-by and meeting with the same dressed teenagers. Everyone was having fun. We spent the time in a relaxed and interesting way. And this is the main thing at parties.

For me, such events are a way to escape from my daily routine and spend time with friends. At such moments, everyone can get together, discuss topics of interest, just chat. After all, such time spent with loved ones is valuable and unforgettable.

Very successful pizza about idle time, but very tasty stuffing. In this pizza no ready semi-finished products were used — I cooked dough and sauce independently. I think, at all it isn't necessary explaining why such completely house pizza is 100 times more tasty semi-finished, and the charm consists in that, as dough and sauce can be prepared in advance and then all preparation takes only a few minutes.
