A suitable occasion to rejoice your parents with a gift of love poem can be the birthday of one of them and of course on the day of their anniversary. Mothers day and fathers day should also be celebrated with the same spirit. In some families people specially write verses in praise of their parents to read whenever there is a wedding ceremony of one of the kids to make them feel proud. An occasion does not need essentially be there to show love to your parents, it may only be a family get-together where you recall with your parents and siblings the wonderful memories of your childhood. There may be some events you remember when things were tough but your parents helped you through the hard times, you can illustrate them in the poems you write and amaze your parents with the fact that you have not forgot whatever favors they gave you.
If the love poem is written for father it contains admiration for his tireless work that means to provide his children with good education, home, food and other necessities. A father is tolerable, caring in his own special way, he may not be as expressive as the mother but he feels exactly the same love and concern for his children so there is the need to tell him you identify that love, in your poem. On the other hand children spend most of their time with their mothers, who love deeply, scold harshly, they worry extremely but in the end they make you what you are. However long your poem goes you may never list down the qualities of a mother.
Your poems will be a joy for them even more as they get old, because this is when they want more attention and love just as they provided you with, in your childhood. These poems convey ones feelings for his parents along with care and respect and make them feel important and still the major blocks of the family and that you wish for their long life.
