не уверена , что всё правильно, но хотя бы смысл понять можно
1) busy SO ? 2) have LUNCH ?
Also, MUCH sounds better in negative contexts.
Tatiana, “busy so” is not idiomatic. And there should be no article before “dinner” in this case. It takes the article only when referring to a dinner as a special occasion, as in “last Saturday I went to a dinner to benefit cancer survivors”.
