1. What makes an 18th birthday special for your grandson?

The age of 18 is one of the critical points in the life of a young individual, a transition between adolescence and adulthood, full of expectations, interest, and prospects. It is a period he starts perceiving the world in a different light and initiates more decisions that will determine his future course.
Herein lies the meaning of his 18th birthday:
Legal adulthood
He is now a full-fledged adult and with rights and responsibilities associated with the new status.
Freedom and more responsibility
He starts to feel independence in practical and substantial ways whether it is a vote or career choice, driving or even moving out.
A deeper sense of identity
He begins to learn who he really is at this age, his values, his goals, his passions, and what type of person he wishes to be.
The process of gaining independence
He starts to be in charge of his life, to know how to combine freedom and responsibility and to develop to his own strengths.
The start of his life creating his own future
This is the time he is going to begin creating the future he desires whether he decides to study, work, travel or take new directions.
As a grandson, it is fun to be 18, yet it is also hectic. His tender and considerate words can comfort him and give him a boost and a reminder that despite the direction of his life, he will forever be supported by a solid support of family love. Your happy 18th birthday grandson’s wish can offer him hope, self-belief and a positive touch when he takes the next step towards the next stage of life.

7. Tips to write your own personalized birthday message

In case you desire to make your message to be uniquely yours, personal touches will definitely help. An individually crafted wish is a souvenir- something which your grandson can store away in his collection.
The following are some of the elements that can make your message memorable:
• One of the most significant things to you.
Remember an experience in childhood--his first steps, when he made you laugh, some special day he spent with you. The subjective recollections are warm and authentic.
• A trait you admire in him
Tell him what you see in him, his gentleness, his humor, his will, his inquisitiveness, or his strength. Young adults should be reminded about their finest attributes.
• A piece of life advice
Tell something you have learned over the years: the need to be truthful, strong, appreciative, or patient. The wisdom of the grandparents is of actual value.
• A blessing for his future
May God bless him and bring him happiness and prosperity and the braveness to achieve his dreams. Blaming words remain in the heart.
• A reminder that you are going to be there when he needs you.
However old he is, he will always remain your grandson-and your help will accompany him through all the phases of existence.
Even a couple of personal lines inserted into your message can turn a mere greeting into something that he keeps all his life.
