So this is the question:

Instruction: Complete the sentences. Use the past progressive in the while-clauses. Use the simple past in the when -clauses.

When my best friend (call) _______ last night, I (wash) _______ the dishes.

My answer:

When my best friend called last night, I was washing the dishes.

But i'm not sure about that. The clause "my best friend ______ last night" can means during the call or make a call. Since the instruction said when-clauses must use the simple past, we still have "I (wash) _______ the dishes." Which is, it must be during the wash isn't it? And we have to use past progressive on the last sentence.

So, what is it? Please help me. Thanks.
