I think everyone from time to time gets this feeling, esp. on Fridays!!!! And esp. if they have evening plans to attend to.
One can love their job so much, yet we all get that restless feeling at times where we also cannot wait to get off and play.
All work and no play would make us all into boring people after all.
Hopefully by now you are having your fun.
Have a great weekend OP.
Remember: Sunday is Fun-day.
