Birthday Letter

Birthday’s are anniversary celebrations of the day on which an individual comes into existence or the day he/she is been created.

In writing a birthday letter, ensure that the letter is written in a manner that touches the heart of the reader. To make it memorable, you could include a personal tone when necessary, add humor and show your excitement for the event. Be conscious of the tone you use and be aware of the relationship you share with the recipient, this serves as a guide on what to write and not to write in a given situation. Use nice words and avoid being formal with close family or loved ones (you could include memories and stories you share with them). But, when it involves colleagues or business clients using a formal tone is more appropriate.
