     In my opinion, the weather is one of the key you have to take into account when you plan your holiday. For example, it’s unwise to go to a sunny hot country during rain seasons if you want to sunbathe. As for the most favourable weather for a holiday, it depends on what a person wants: some people fond of cool weather, other keen on hot. Some prefer snow other just light breeze. So, I agree with a famous proverb: Tastes differ.  

    As for me, I also think that there is a direct link between the weather and a person’s emotional state. I have heard that some scientists are sure that lack of sunlight leads to depression. Here I can put a personal example: my granny usually feels depressed, ill and has headaches in November. This month has least number of sunny days. Also it is well known that people with mental diseases feel worse in spring and in autumn.

    I have guests a few times a week. All members of my family are very sociable and communication is very important part of our life. I suppose that hospitality means being polite, friendly and take care of guests. Host and hostess should feel comfortable themselves and make their guests feel comfortable too.
