You must be tall, dark, handsome, and an incredibly HOT cowboy. You must love kids and leave the house in the morning with your 18 month old son for some one-on-one time feeding the horses.
You must then return to the house and cause before-mentioned son to squeal with delight by putting him in the swing and pushing him over and over to his utter contentment.
Oh, and you must be willing to periodically check for snot running down his upper lip and wipe it promptly with your hankie.
Yeah, that pretty much does it for the ol' ticker. Hubba-hubba! (Seriously, I don't know why, but it pretty much reduced me to a lovey-dovey mass of hormones this morning. But I'm not complainin'!)
