Not So Smart Sometimes

Why am I always so slow to get a rule to stay in my head? You would think that a submissive would always, always, always obey every rule. It's not that I don't want to it, it just hasn't stuck in my head yet. But...why? Stupid, stupid, stupid. No other way around it, I can just be plain stupid. I get a spanking when I don't follow the rules, and it is something I want to do. So it's just that I'm stupid sometimes. Wouldn't a smart person put two and two together and obey all rules at all time, ESPECIALLY if it's something they like and take pride in? I honestly don't know how my Master puts up with me. Hopefully the spankings will put more brain cells in my head!
