Dear
Neha
Thank you for your cordial invitation on the occasion of your sister’s wedding. I, however, regret my inability to be with you on this happy occasion as we shall be leaving for Singapore for summer holidays on 1 May, 20XX. Please excuse my absence. Do convey my regards and best wishes to the couple.
Yours
Satyavrat/Suresh
sincerely
