The pleas of her family were echoed by relatives of U.S. tourist Eugene Benoit, currently traveling in South Korea visiting friends.
He, too, has been struck by the calm atmosphere, but his family members are unnerved.
"My wife and daughters and my mother are all saying: 'Come home early, it is too dangerous there!'" he says. "But I say there is nothing to worry about and I am sincere about that."
Why tensions have erupted so suddenly -- and why now -- is a question many in the international community are struggling to answer. For Canadian teacher Leigh MacArthur, who has lived in South Korea for almost a decade, all fingers point to the North's inexperienced new leader, Kim Jong Un.
"I feel that he is having to prove himself to his military -- some of whom I'm guessing served under his grandfather -- that he is in fact in charge and still has his grandfather's and father's ideologies at heart," he says.
In Samcheok, in the east of South Korea, where MacArthur now lives, he says people are still very much carrying on with their lives, with no panic buying of essentials and people still focused on their day-to-day business.
He, for one, is determined to follow their example -- for now.
"I made a choice years ago that I would not live in fear or worry about the situations that may or may not happen in regards to North Korea," he said.
"I haven't thought of leaving the country, not yet."
