i'm telling you, lack of sex makes a person ill.  many a parent take regular sick days off from work because the only possibility of extinguishing the raging flames of desire is when the children are in school.  it is safe to conclude that this is also the reason why we see a lot of parents looking less than joyful during the summer holidays.

some days parenthood makes you thankful for the candid humour your own children bring into your life.

some days you want to kick your own ass for breeding.  i think we're purposely built not to contort for this reason.

you'll never know your own capacity for love until you have children.  also, you'll never understand why some animals eat their young until you have children.
