A smile is the light in your window that tells others that there is a caring, sharing person inside.
Don't assume that money, shelter and creature comforts are enough to demonstrate your love. Nothing can replace your presence, your hug, your smile, your touch - you!
SMILE! In every language, in every culture - it is the light in your window that tells people there's a caring, sharing individual inside and it's the universal code for "I'm O. K. - You're O. K., too!"
