У Игоря круглое лицо, как и у всех, немного длинный нос и большие радостные серые глаза. Eго лоб открытый. Его волосы не очень короткие, но это не длинные. Они прямые и черные. Я думаю, что он похож на своего отца. Игорь очень активный и творческий, жизнерадостный и любознательный. Но самое главное - он надежный. Мы проводим много времени вместе. Мы ходим гулять, играем в теннис, смотрим телевизор, делаем вещи, которые нам нравятся. Я люблю моего друга.
