It makes complete sense to me. You don't even need to explain. You stated that she was pretty but didn't get the hype of some comments and fair enough. I think Scarlett Johansson is one if the most beautiful women of our time. My sister in law thinks she's pretty but boring. She just doesn't get it. She finds Kim kardashian that amazingly beautiful whilst I think really? She is pretty but meh. It's not that you don't find tully attractive, but she just doesn't rate as high as others would. I don't think there is a wrong in what you are saying, nor do I take it offensively either, no one should. I never understood why people went on about jasmine, like you with tully, I just used to think, yeah she's pretty... Yep that's it. I'm not going to defend myself for it and neither should you
