in my country, we will be having a 2 day Muslim holiday. I have mapped out all the programming tasks I need to attend to during those days and thinking of staying back at the office but my gf is thinking of coming over. this will mean not achieving all the tasks which is a problem as I Dont know when next such holiday will be.

how best do I tell her not to come?

I girlfriend frowns when ever I spend so much time with my system coding. she doesn't just get it that my system was my first love before she came into my life.
