In
almost all circumstances, who really can? Hehehe.
"He that is not jealous is not in love." Hehehe.
~St. Augustine
"Never love unless you can
Bear with all the faults of man:
Men will sometimes jealous be,
Though but little cause they see." Hehehe.
~Thomas Campion, "Never Love"
Note: Can't speak for females, 'coz dunno how they'd react.
