Hi Emma H....my interviews last about 30 - 45 min. I show them around...sit down at kitchen table...I lay out my program...vacation.. .all my rules...they ask a few questions...then I politely say...."great....if you get home and think of anything else, please give me a call"....please let me know what you decide as I have other people I am interviewing for the spot...DONE....Never really had a problem...have to admit though...ONCE ...my daughter did text me something....I heard my phone....(excused myself for a min.)...and texted my daughter asking her to call in 10 min. When she did...I replied with...."YES DEAR...I WILL BE THERE SHORTLY".....THEY GOT THE HINT! It's not rude....all was said and done....it's called "BYE BYE"....
