I was eating lunch when
I saw Mr Bean.
I was running when
I fell.
We were walking to school when
we saw a cat.
They were playing games when
the storm started.
They were watching TV when
he arrived.
She was playing Blooket when
the doorbell rang.
He was doing his homework when
the phone rang.
He was listening to music when
he started dancing.
I was playing a video game when
my dog barked.
He was swimming when
he saw a turtle.
