Are relationships between a teacher (primary school) and a parent (single) just discouraged or a disciplinary offence?
Both are single. The child isn't taught by the teacher in question. Will most colleagues of the teacher resent the parent? I'm guessing school social occasions would be awkward.
As for the question which is bound to be asked - why do you care? Because I do.
And no, I'm not a troll or a goady fucker. I am a name changer though.
