Hi. This is an informal letter  .

The body of letter goes like this

Hi  friend hope u are enjoying ur life and luck find u in best  state of mind. My exam have been over and wanted to share my experience with my near and dear one so I was planning to come to ur place to enjoy my vacation.

Do you remember our childhood memories of playing together, gossips together. Once we bought a toy car from our money and had much fun .We have grown up but my love and concerned for u remains the same.

If u are free and your exams are over then we can spend some time together to rejuvenate our memory.
