Communication is very important in our daily life and writing a letter has a great impact on building social relationships. The students of Grade V were taken on field trip to the Post Office. Students observed the cabin of the postmen where a couple of postmen dressed in their uniforms were sorting letters. One of them showed the students different sections like assembling & sorting of letters according to the cities and states. Students were also shown different types of letters, postcards and inland letters. The postman also showed them the processing of stamping letters. Students posted the letter in the Post Box and felt excited.
