Hello, Mattew, started bird-watching as your new helpful hobby. It sounds really colossal!
As for your questions, you should join local environmental organization in your city. I think you easily can find it. I consider that you need to be any age to do volunteer’s work because it’s kind of good business and it’s voluntarily. You’ll need to be kind, patient and able to help people or animals and etc. I think there are many summer camps. There are linguistic, science, sport and tourist camps in Russia. All of them are very popular with children . fun and learn new things there. I have gone to different camps twice. And I think they’re the best place to spend summer holidays.
By the way, in what university has Tom gotten into? Which subjects is he going to study? Will he live in the dormitory or at home? Well, I have thougth about my future career many times and now I'm sure that I want to be an English teacher because I really love children.
What about my parents, I've asked them for advice two or three times. They are the doctors but this kind of job isn't for me so I wouldn't like to follow in their footsteps. By the way, holidays that you’re spending with me in next month. Well, I’m also looking forward to seeing you. As for weather, it can rapidly change so if I were you, I would bring both warm and light clothes. To be honest, you don’t need a lot of money but if you’re going to buy souvenirs, you can take some of it. Of course, I’ve arranged exciting things for us to do I’m sure it’ll surprise you.
