Preschooler's Comments

Yesterday while picking up Kiana from preschool, as we were walking away I overheard three boys wondering why I used a cane.  One boy said it was because I was old.  Another boy said it because I was injured.  And another said it was because I was too skinny, which I heard him say several times, as if he knew the answer.   Kiana didn't seem to hear, or if she did it didn't seem to phase her, but I wonder at what point she is going to wonder why I'm different, or if her classmates ask her  Another day I had a boy ask me why I only used the cane on the sidewalk but not on the grass.  Three and four year old children are so observant.
