Noah tended to roll with things, he rarely got worked up over crap in his life because honestly there was a lot of crap and if he freaked out over every little thing...that's all he would do. He liked Lo so far, Noah honestly didn't know who he was when he was a boy but as a girl he was alright.
The thing was Noah never had any modesty to begin with, he was never ashamed of his body but he didn't think people wanted it either. So those feelings were carrying over into his new life as a girl; which was part of why he didn't notice Lo checking out his boobs when he flashed him.
When they started walking a sales girl handed Noah a basket for his things, which he thanked her for and dumped them into as he walked, saving Lo from having to make sure he didn't drop things. Noah smiled wide at Lo and nodded. "You are tiny, it's cute." He was teasing a little bit, knowing how most people react to being called cute. Noah blinked at Lo's suggestion and then shrugged. "If you really want me to, I can tell you that." He said, happy to be of some help since Lo had helped him.
