I've noticed that more and more, I've been communicating with (usually younger) students who don't know how to approach someone older in a polite or respectful way. I'm a professional teacher, and even though many of my students are non-native speakers, whose grammar lapses I can forgive, I sometimes get messages that are actually rude. As if I'm someone (faceless of course when online) whom they can order, or demand something of, they approach me in a way that makes me not want to work with them.
I would like to urge all students to consider how you write to a potential or current tutor, and I'd like tutors, no matter your age or level of experience, to consider responding only to students who can write politely, or point out to them their lapses of judgment. All of us, tutors, parents, adult students, youth, should approach this business from a position of respect. This is not a social media with anonymous strangers, nor a forum for hiring or being hired devoid of human respect. This is not Craigslist. When I am told "well, change it!" (a lesson needed to be re-scheduled), I feel much less likely to work with someone who speaks that way.
