A Tiny Question for My Big Boss

I’m having one of those dull office weeks where everything is going fine and nothing exciting happens. But here’s the thing: today, my big boss (who’s also my dom) asked me to run an errand. The weather was just right - cool enough that a jacket would be needed but warm enough for it to feel like an adventure. As I walked out with him watching from his office window, I felt this sudden burst of excitement... I could imagine all sorts of things happening after this task was done. Could he really do something so daring here in broad daylight? Would there be a reward waiting somewhere hidden? When I get back to the office tonight, I’ll ask if anything is planned and hope that this little fantasy might actually happen. Is it normal for me to feel this way while just running an errand? Should I even dare to dream of such things in public?
