Like being taken in by strangers and helping to carry their bags.
And why shouldn't you? Because you maybe be helping them traffick illegal drugs.
We know of at least two cases of women who were caught and arrested in foreign countries for having in their possession illegal drugs.
One was in Australia a couple of years ago, and just recently a Mass Communication student now serving time in a Japanese prison.
Both claimed to have been duped by Iranian men.
The woman in Australia was later released. The Malay Mail (under Rocky) did an extensive coverage of the case.
Anyway, here's a Bernama story quoting Foreign Minister Syed Hamid Albar cautioning women travelling alone to not trust strange men they befriend.
KOTA TINGGI, Oct 7 (Bernama) -- Foreign Minister Datuk Seri Syed Hamid Albar advised Malaysians, especially women, who wish to travel abroad to be more careful and not to help carry bags or packages belonging to other people they do not know.
He gave the advice because many Malaysian women had been arrested and jailed overseas for carrying bags or packages containing drugs.
"When travelling, take extra care. Don't simply help people who ask for help. Don't simply carry their bags when we don't know what's in them," he told reporters after hosting a breaking of fast at his residence here yesterday.
He said that if one had been found guilty by a court overseas, it would be difficult for his ministry to get them released.
He was commenting on Raja Munira Raja Iskandar Shah, 22, who was sentenced to seven years and four months' jail by a Japanese court for attempting to smuggle several packets of syabu at the Narita International Airport in Tokyo on Dec 20 last year.
Raja Munira, a mass communication student of a private college in Kuala Lumpur, alleged that she had been duped by an Iranian man she had just known.
Syed Hamid said he had ordered the Malaysian Embassy in Japan to visit the woman and gather information pertaining to the case.
So, ladies (and gents too) -- you cannot be that trusting or naive or stupid.
