Really not sure if I'm being overly sensitive here. My DD (8) has a music lesson each week and the teacher comes to our house. With the colder weather she's decided to teach from her home. I'm a bit put out by having to travel as my other children have clubs etc and we deliberately choose a teacher who came to us for convenience but willing to give it a try as it is temporary.
I've since found out she has a lodger who will be present when DD is there. The teacher can't understand why I'm uncomfortable with the arrangement which makes me wonder if I'm being unreasonable.
