I was raised in a dinner-table house LOL and I carried that with me. I guess it's all what you're used to! Lunch is usually with co-workers but we all sit at a table, and dinner is with nice plates at the dining room table and DH and I talk and laugh thru it, it's my favourite meal of the day!
I like the little bit of formality, I took time to prepare a nice meal and we sit down without any distractions and enjoy it. We eat around 7 pm so there's nothing good on tv anyway
