In formal letters if you are writing on a plain sheet of paper, it is normal to write your name, without title, above your address at the top of the page, either on the left or the right–hand side of the sheet.
When writing your own address, it is of course quite correct to place commas at the ends of lines, if you wish.
8) Soy feliz de compartir cada instante de mi vida a tu lado. 12) Tarda una hora en conocerte y solo un dia en enamorarme. – It took me an hour to know you and only a day to fall in love. These letters for special occasions require careful attention to expression; some even follow a format which is rarely deviated from. The corresponding envelope should be the same colour as the letter and preferably the size that is known in Spain as "formato americano" (226mm X 114mm).The letters in this service of Letter-Writer Deluxe Spanish are of the commercial and special occasions types as these require greater skill in the writing and cannot simply be direct translations of English correspondence. The A4 letter should be folded into three equal parts, which will then fit snugly in its envelope.In a letter to someone with a title, in a business for instance, this is placed after the addressee’s full name.Note some of the courtesy titles that may be used to men and women.
