You can write a compound sentence using FANBOYS:
F —> for
A —> and
N —> nor
B —> but
O —> or
Y —> yet
S —> so
i.e.
1- The boy laughed, and the girl giggled.
2- The brown squirrel ran up the tree; hence, the dog did not bark.
3- Julie wanted a piece of cake, yet her mother said no.
4- It was bedtime, but it was still daylight.
5- Do you know Mike; do you like him?
6- We could go to the movies, or we could walk to the park.
