I found respite more relaxing than some of my carers on occasion, they seem more laid back as they are only there short term. Just see it as a distant family friend and your meeting for the first time, anything to make you feel more comfortable around them, I'm sure they will be nice. Keep posted on here plenty of us here if you need us., good luck
I would add take your phone contacts with you. Take comfort items. I hope it is an positive experience.
