Sorry XXX,I really want to visit you sometime,but certainly not this week because I have other stuffs to do for rest of the week.First of all,my english teacher assigned me a new homework assignment due next monday,and I have a lab report for phyiscs due next week,more importantly,i have a midterm exam next friday that I must study for.To put words in a netshell,I am super busy this week so that i have no free time at all as you can imagine.
I would love to visit you when I am freed by homework assignments and tests and thank you for your invitation.
