Ma'am. Sit allllll the way down.
Unless you are able to produce and contribute sperm cells in the life-creating process, you are NOT a father, regardless of what your household duties are. Hard as you may work, all you are is a single mother who doesn't have a male role model/father figure in your child's life. This is not to discredit all you do for your child; this is to smack some reality up in you.
You cannot be a father. There are things that only a man can teach his children. Please just accept that and move on with your life. No need to sully the day for real dads with your bitter feelings toward your baby daddy. There are quite a few men who take their job as dad very seriously and your encroachment of their day is rude and annoying.
And fellas, please note that this same sentiment applies to you. Regardless of how useless or ratchet or just plumb not there your baby momma is, you are NOT a mother and will never be. Again, there are some things that only a mother can teach her children and you don't have it.
Men and women are DIFFERENT. We just are. And each of us brings something unique to the parenting table. Enjoy your role and work it to the max and your child will have a fighting chance in life.
Besides, as The F$%k-It List so eloquently put it:
Amen, sister. A-MEN!
*smooches...knocking multiple chips off of multiple shoulders*
I'm sure my opinion won't be popular but whatever. deal with it.
