when Chelle was 5, her parents bought a great dane puppy named Cezar. but Chelle named him Cement, because he was big and grey. they was inseparable - playing together, sleeping together, she treated as her best friends and had more fun playing with Cement than with other kids. but that's why she had big problems with finding her place in school society. Chelle was good girl. nice and cheerful. but she didin't really care for other kids, didn't wanted to play with them. Cement was the one who mattered. that's why other kids started to think that she's kinda weird... but she didn't care.
but great danes live very shord. Cement died after 7 years, when Chelle was only 12. she was strongly depressed, as much as only kid could be after losing best friend. she started to be quiet, sad, apathetic. rarely smiled. she didn't have other friends and her sister Rita was quite popular girl in school, so she felt even worse. one day school teacher called Chelle and her parents to say, that Chelle has all symptoms of depression and should be covered by the psychogist care. for a few years she had reguar meetings with psychologist. but she still had problems with other kids, she just didn't know how to act, how to make friends.
after years she changed a bit, grew up and started to fix everything. she gain some self-confident, started to work in dog shelter, and even she has some friends now.
