Remembering Childhood and Running for Shelter

It's a shame when you ask a student "What do you remember about your childhood?" and he answers, "I remember fighting in a war." (in Vietnam)

Question for my ESL students: "When do you run for shelter?"

My example: I run for shelter when I hear gun shots.
or
I run for shelter when I'm being attacked (unless there's no exit), in which case, I stand and fight.
