Your children are very, very fortunate to have you for their mother. If you display the strength of character, before your children, that you have communicated in your response, you will make them wealthy in how to deal with the problems of life.
If I could redo any part of my life, it would be how I responded to some really dark days, keeping in mind the effect it was having on my kids, because they were hurting, too. (Indelible impressions.) We're just human, and pain comes out in "funny" ways.
