Dear Soma,
I hope you are having a good vacation with your family.I know you would be a little busy for preparing for the upcoming exams but please take out a little time to spend in my house.As you know we have exhibitions right after the vacations and mam has asked to submit the synopsis and ideas by monday of next week.As both of us are planning for a science working model based on the topic I want you to come to my house for a little discussion on this.Also we can finish up our homeworks together at my home.Please reach over here by 6 o'clock in the evening on Thursday if you can.I will be waiting for you and if you might be busy on that day please let me know thus we can decide some other day to discuss on it.Thanks!
Yours (name)
