After my recent conversation with someone I started to wonder about my own ways around conversations... Some examples of conversation are below... Can anyone tell me where I would be going wrong? Or is the Mrs just being an ignorant wench?

Reubs: So, how was your lunch? Did you have anything nice?
Miss S: A sandwich.
*BOOM! Conversation dead*

Reubs: So, Miss S, what have you got planned for your day off? Anything exciting?
Miss S: Just this and that.
*BOOM! Conversation dead*
