A doctor takes care of the patients,

a driver drives the car,

a potter makes the pots,

A tailor stitches the clothes,

A postman brings us mails,

A pilot flies the air-plane,

A fisher-man works

with his nets

to catch the fish,

A teacher teaches

the students,

a carpenter makes

furniture,

a cobbler mends

the shoes,

Do you think all these are possible,

If the farmer does not sow the seeds?
