Reflexive pronouns and the past continuous

We use reflexive pronouns when the action affects the same subject who performs it.

He looks at himself.
When a person does something on their own:

I myself did all these things.
She did the project by herself.
Past Continuous
We use the past continuous to describe things that were happening at a specific moment in the past:

• Subject + verb be in past + verb ing + complement. She was walking when she saw herself in the mirror.

• Subject + verb be in past + not + verb ing + complement. They weren’t cooking when the food burned.
  ? Wh + verb be in past + subject + verb ing + complement + ?
