Lola, you can't question your parenting, obviously, or the tween wouldn't have been so sweet. That's awesome!
Sorry D25/23 were busy or had their reasons (like even just forgetting)but don't feel hurt. Know that we don't fully realize our parents' love and sacrifices until we become parents ourselves. Give them a few more years and you'll have a much closer relationship with them, especially true for moms and daughters!
