In my free time…oh, wait…I’m married with two children. I don’t have free time. I was born and raised in Oklahoma and bleed crimson and cream through and through. On my first date with my husband I asked him a simple question, “OU or OSU?” Lucky for him, his answer was “OU.” He still doesn’t believe me that we wouldn’t be married today if he had answered the latter.
