Yesterday

Yesterday was a beautiful day with sunny weather, neither hot nor cold! I got up at 7:00 o’clock, I and cooked breakfast, which consisted of boiled milk and egg, and toasted bread, and quickly washed and dyed (Did you wash and dye your hair? Did you take a shower and dry yourself off? Did you wash and dry the dishes? I don't understand "quickly washed and dyed" here.) then went before going to the university. Now Russia is no longer cold, the snow has all melted, and there is dirt everywhere! A lesson I try to prepare all seminars.(What lesson do you try to prepare for all seminars?) After class we I walked around with my friends in the park and feed fed the pigeons. In Russia there has always been so many pigeons, and everyday I see how they are fed by Russian grandmothers. And I often see parents with their children playing in the park and feeding the pigeons, and the children chasing chase the pigeons! And Everything was so interesting; and I remember my parents and my childhood!

If you say 7:00, you don't need "o'clock." You only need it if you say "7 o'clock."

Boiling the milk and egg, as well as toasting the bread, is part of cooking breakfast.

Did you boil the milk and egg together? If not, you should say, "...which consisted of boiled milk, cooked egg, and toasted bread...."
