Dear Shaina, the act of yours committed in class 2nd ,i.e., might be at the age of 6 or 7 years, can’t be termed as stealing chalk. Although if our child would do something like this then we will certainly make him/her understand that never take anything without permission but in the heart of our heart we will know that this act was just out of curiosity. You were curious at that time to know how it feels like to hold such colourful chalk and write with it. At this point of time when you have grown up, you should not bother yourself. Rather your should understand the mentality of child.
