I don't hate portraits at all cause it always reminds me of the uniqueness in each individual faces and that not everyone's the same. If I get asked everyday, which I don't at all, then sure I'll be annoyed by it, but I'll take this advantage for practicing in this field. To have a person asking for a portrait as a live model would be awesome cause then you could set up the composition however you'd like. But this is all in my opinion.
