To all of you reading this who are interested but don’t have home assistant (yet): I just set a timer for as long as the laundry takes. If I can’t go get it when the timer goes off I will place a “memento” somewhere (for example placing something on the ground in my way where it doesn’t belong) so I remember. The “set lighting to hell until I do it” solution sounds neat too, though. =)
In writing, yes. But when spoken the emphasis is different. If the “fahren” is stressed, then you are driving around something (umFAHren). If the “um” is stressed (UMfahren), then you are talking about property damage or murder.
