Mrkácek Ciko (1982)

Roman Hlava grew up with his diplomat parents in Latin America where he had been home-schooled by his over doting mother. The over indulgence of affection and praise has given the boy an over confidence. This is quickly squashed by his new peers when the family returns to the Czech Republic. This leads to neurotic tics and the nickname Mrkácek the 'Blinker.' A stay at a children's camp provides new friends, acceptance, an appreciation of nature, a new outlook on life, and loss of the tics. (I did my best to piece together machine translated bits and pieces. I hope it bears a decent reflection of the movie.)
