2 little thoughts
1- Andy has a couple chicken pox scars on his face.
2- I watch a lot of asmr lol specifically the lofi variety. I was just thinking it'd be cute if, Howard likes to just sit and listen to/watch Andy do his little things that he does. Typing, writing on paper, playing calm, quiet piano. Not sure what else. Just, concentrated tasks. I think Howard finds it calming.
