And another scene from Seven Pillars of Wisdom (is haz crack!) xD :
"The argument had delayed us, and consequently we only reached the foot of the pass at dark.

Saleh, the son of poor old Mohammed, our jester, was the proper lad who had carried Wejh by assault on Vickery's field-day.
'Cheyf ent? (How are you?') said I earnestly twice or thrice. His eyes sparkled at the Juheina manner.

He took me up with another of his long bursts, many more than twenty this time. So I gave up trying to learn how many are the possible repetitions of salutations in Wadi Yenbo.
