My son came back from playgroup tired and dropped straight on the bed, his feet hanging in air with shoes on. I asked him, if he wants I can remove his shoes for him. The kid raised one foot, I untied the lace and waited for his comment. He said remove my shoe, I removed his shoe and again waited f or his comment, he again lazily replied remove my sock. I removed his sock and waited, absentmindedly he said remove my foot. Everybody present in the room smiled.
