>>3985276Despite his hemophilia, Alexei was adventurous and restless. Doctor Eugene Botkin's children noticed Alexei's inability to "stay in any place or at any game for any length of time". When he was 7, he stole a bicycle and rode it around the palace. Shocked, Nicholas ordered every guard to pursue and capture Alexei. At a children's party, Alexei began jumping from table to table. When Derevenko tried to stop him, Alexei shouted, "All grown-ups have to go!" Recognizing Alexei's energetic nature, Nicholas ordered that Alexei be allowed "to do everything that other children of his age were wont to do, and not to restrain him unless it was absolutely necessary".
