Hello my dear and respected teachers,
Suppose there is a bull standing on the road.A child is waiting for the bull to go.He's afraid of the bull so can I tell the child like...
1 : "hello, don't be afraid of the bull,just go aside"?
2 : "Walk aside a car is coming" correct?
3 : "Don't use swear-word OR swear-words?

Hello my dear and respected teachers,
Suppose there is a bull standing on the road.

A child is waiting for the bull to go.He's afraid of the bull, so can I tell the child:
1 : "Hello. Don't be afraid of the bull. Just go around it."
2 : "Step aside, a car is coming."
3 : "Don't use swear words." Right. Only use swear words if you have a dirty mouth.
