In this case referring to going somewhere.
Does "as early as possible" mean -
YABU - as early as you can possibly get up and go. Set your alarm for stupid o'clock, wash, coffee, dress, straight out and off.
YANBU - the earliest convenient time taking into consideration various factors such as avoiding school traffic, not being too tired, the time where you're going opens etc.
I say settle an argument but we're not arguing or anything. It's totally trivial.
