And in practice, we can be so cruel to teachers. Speaking personally, I went to middle and high schools where respect for authority wasn’t exactly at the top of the priority list. And even if the students weren’t throwing chairs at each other and/or the teacher, they likely still weren’t being decent.
It’s that it-factor, that natural chemistry that’s lacking. You always used to think that when people talked about ‘the spark’ they were full of crap, but there you are: sparkless and uninterested. Go on a second date, then a third, then a fourth. Wait patiently to start feeling attached. Keep waiting.
