Did I go about this wrong?
I'm new to cello, and have been taking lessons for about 6 months now privately and was renting my cello from my teacher who also has a business selling cellos. When I started, they didn't have any student level cellos and I ended up renting an advanced level cello at $70 per month rather than the $50 it would have been for a student one, which was fine.
My rental agreement was for 6 months so about a month ago my teacher approached selling me the cello at the total value of the cello minus rental fees, however there are some noted repairs done on the cello and it was not in mint condition. I said I would discuss it with my husband.
Ultimately, we decided that it was more than we wanted to spend on an instrument (it was a beautiful cello, but again a higher level instrument than I need) but was almost $4000. I don't intend to ever become a professional, this is a hobby and something purely for my own enjoyment of playing.
I ended up finding a cello through a luthier who does restoration, and got a beautiful cello kit for a price I was much more comfortable with. And was happy with the sound and was able to try multiple cellos for comparison with the luthier.
When I told my cello teacher that I discussed the cello purchase and that we were going to go a different route with the purchase. During my next lesson my teacher let me know that my decision, in their opinion, was disrespectful, and that students usually bring their new cello or trial cello to their teacher for advice and essentially that I hadn't consulted them. Made an offhand comment about "but maybe you know more than I do".
Honestly, consulting them is not something I would have done, as they sell cellos and to me, it's kind of a conflict of interest if they are trying to also sell me their cello. As well, the student/teacher relationship is only 6 months, it's still relatively new. Showing them the new cello prior to purchase wouldn't have even been a possibility as it was purchased 4 hours away.
So now I feel awkward going to them for lessons because they were very serious about feeling disrespected... And honestly.. I feel kind of off because the whole situation seemed oddly territorial.
Am I reading the situation wrong? Did I commit a string instrument faux pas by not getting approval/advice from my teacher before purchasing my own cello?
