Trinie,
I did not say its wrong, I personally find it distracting, and best avoided. However again I said its case-by-case basis, it doesnt mean I condemn, only I think, if given a choice, I will avoid this kind of scenario. Especially Teacher-student or Boss-subordinate scenario. Sure, I seen many good examples, but there are way alot more bad ones for every one good union. I guess it might be a matter of what I'm exposed to.
