I received your invitation for the celebrations of your forthcoming birthday on the 19th of this month. I am very happy to receive your invitation. It is very nice of you to remember me on this occasion. I wish you heartily in advance for "A Happy Birthday and many Happy Returns of the Day."
Unfortunately, I am busy at the moment due to my commitments at my office as inspections by the head office representatives are going on. I am indisposed for a week. I promise to attend your function without fail in future. Wishing you again for a Happy Birthday,
