She studied hard ... she failed.
but
All the cafes were full ... it was national holiday.
because
She was crying ... her team lost the match.
because
I called him ... his phone was turned off.
but
We couldn't find a taxi,... we walked home.
so
They wanted to win ... it was impossible.
but
I woke up ... there was a noise.
because
.... she is nice, she doesn't have friends.
Altough
.... it was cold, she wan't wearing a coat.
