I was swimming in the ocean

when I was attacked by a shark.

I was writing a story

when my pencil broke.

I was drinking milk

when my friend made me laugh, and the milk came out my nose.

I was eating spaghetti

when I spilled tomato sauce on my shirt.

I was talking to my friend

when the teacher told me to be quiet.

I was sleeping peacefully

when my brother woke me up.

I was washing my face

when I got soap in my eyes.

I was watching my favourite TV program

when the television broke.

I was taking a shower

when the water suddenly stopped.

I was riding my bicycle

when the wheels suddenly fell off.

I was fighting a crocodile

when it bit my arm.
