DOCTOR

One of my friend is Doctor, as usual we both were very busy with our work and could not able to get time to visit each others house.Doctor has told me so many time that once we will have dinner togather,but neighter of us get time. One day doctor thought to give a surprise to me and he send an written massage to me,but  I could not able to read what he has written ,so I thought that lets go and meet some medicine shopkeeper as they are well versed with the doctors handwritting, I showed the paper to the madical shopkeeper,he tried to read the paper and without telling anything he given me six cough tablets  ,with my surprise I paid the amount and left the place by thinking that what happens to the doctor,unecessaryly why he prescribed the cough tables.Later next day morning he called me and enquired that why I not came yesterday night for dinner when he had send the invitition, then I explained the whole story that how I miss my grand dinner party and got six cough tablets which I was not required.
