If you're walking on a crowded street and you stop suddenly — abruptly and without warning — somebody walking behind you may bump into you. If you experience love at first sight, you've suddenly fallen in love. If you're driving at night and a deer jumps out in front of you, you might suddenly have to swerve to avoid it.
