2Dear x,
Thank for your writing, I have honor of your invitation to the dinner in Valentine’s Day.
Unfortunately, my study is really pressure, I have to absorbin my study, so regrettably
I must decline. I feel sorryabout that. But I think you can date other people to dinner with you.
In addition,Valentine’s Day is indeed the perfect day; however, it is suited to a couple,not for students. I think as a student should focus on study, because it is ourresponsibility. We shouldn’t belie our parent hope for us. And that we are veryyoung, love is elusive fours, so we shouldn'tbe in love until become a grown-up. I think you should catch on to what I am saying.
I know that you are a friendly, interesting, andsmart boy, so I still wish I can make friend with you. If you have anythingabout study or other thing, you can just call me; I am willing to lend a hand.
Sincerely,
x
