With your comments you disqualify yourself. If this is the way you pretend being a teacher I can understand if students run away or play on their mobiles. I pity you. As a teacher I expect far more intelligence and ability to offer interesting lessons. However, sometimes it would require to go new ways of teaching. Unfortunately you are either too old willing to learn or just a grumpy member here wasting my time. I wish you a lot of enlightenment if possible. And I definitely don't want to have a reply.
I'd say the problems are so-called teachers being incapable to accept new technologies and changing attitudes of students. Sure, if you offer boring lessons, students are likely to use their phones or laptops.????
If you like it...do it. Go for consultation at University Dental Clinic. They will check your gums and bones and give to a time frame. And also a quotation.
I think all better than a Golden Straw.

I would not go for any decision just of majority here in this forum. ????
