We know massages, cleaning, cooking, etc. are fantastic, but what is something you've done based on his likes/dislikes that's more personal?

For ex. my bf and I have been talking about what type of homes we like, what types of decor, etc. he mentioned he really likes how pristine and put together hotels look, esp. their bathrooms. So I went into his bathroom and arranged his towels perfectly, not even a centimeter off (yes I'm a perfectionist haha). Later we were brushing our teeth and when he went to dry his hands he just stopped for a moment and stared with his hand outstretched towards the towels.

He was so happy! I was still brushing my teeth so I had to kick him out because he was ready to kiss me just like that. When I came out he was all kisses. :)

Do you guys have any stories you'd like to share of the personal "little things" that you've done for your SO?
