It had been the end of the day - not Clark's most favourite time of day because it usually meant either saying goodbye to Lois till the next day or trying to come up with an excuse to spend some time with outside of work. Weekends were the worst - she was becoming like a drug and he was addicted but the weekends were now giving him something akin to withdrawal symptoms.
You know, when I read the opening of Yvonne's Addicted, that's what I thought it would be about. Clark being addicted to Lois. Looking forward to finding out how much you're going to milk this notion
