A grievance with the administrative assistant

I don't know if it's just me, but being really patronizing when you're trying to get me to do something is a good way to get me to not do it. Seriously. Now, the first time you asked me to put the start and end dates of the pay period on the time card and carefully explained how to determine said dates, I actually going to do it on successive time sheets. However, since you insisted on explaining it again after I already told you that I know how to do it, I'm now going to make a point of not filling it in. Hopefully this combative streak is something I'll grow out of when I'm older, but for now I have to say up yours. Have a nice day!
