Nadine: I have a big favor to ask you
Robert: sure, what's up?
Nadine: could you vacuum our place when you get back?
Robert: I'll try to do this today or tomorrow morning
Nadine: but vacuuming tomorrow morning would wake me up
Robert: ok I'll do my best to do this today
Nadine: thx ;*
Nadine wants Robert to vacuum the place today. Robert would rather do it tomorrow morning but it might wake Nadine up.
