Ruby bit her lip, concentrated on her the wand in her hand and jabbed it directly at her schoolbag. She jabbed and jabbed. It was hard practicing with the wand and not speaking out loud the spell. Ruby felt as if there were something twisting in her mouth. She wanted to try the spell on her schoolbag, yet she knew that she could not and had better practice carefully or she would do something bad to herself before she could turn her bag into stone.
