Quick night or not!

My wife always laughs at when I say I am doing quick nighter.  I try and explain that a quick night is from 1830 to 0630 the following morning.  This is an overnight fishing trip.  These trips are gone to quickly as there is not much time to do a lot.  Whereas ‘an overnighter’ would be from noon one day until noon time the next day, this is a lot more relaxed and not that quick.  My wife is very understanding of my obsession with fish and as long as I am home more night in the week than I am out, all will be well.  She just finds my terminology funny!
