I felt a pang of guilt and regret inside me, but the giddiness of getting away with something so bold quickly overpowered that dread.

The first attempt to fire up the Large Hadron Collider failed, so the second, successful attempt was greeted with a palpable sense of relief and even giddiness from the many physicists who have labored for more than two decades to get this 10-billion-dollar experiment underway.

Mr. Lorry, you cannot control the mincing vanities and giddinesses of empty-headed girls; you must not expect to do it, or you will always be disappointed.
