A mother's warm embrace.

 Missing someone a heck of a lot.

 Sometimes getting stuck with the "he loves me not" petal.

 Broken Promises

 A father looking into his daughter's eyes for the 1st time.

 A child discovering a bug, and the bug discovering him.

 A brother letting you do his hair, regardless of how ridiculous he may look.

 A sister's shoulder to lean on and hand to hold

 Color blind.
