When someone talks to you, do you explain your thoughts to them clearly?

Like whenever I would talk to someone. I used to be so concentrated on my anxiety while listening to them talk that I wasn't listening to what they were saying so I seem like a dumbass. Today I'm starting to realize that I can explain my thoughts just like everyone else and not just answer with one word but whatever I'm feeling at the time, like if I get asked to look for the controller to the T.V, I would just say 'Okay' but it just hit me that I can and should day more than just 'Okay' but maybe 'I thought it was on the couch right here, I'll look for it' Stuff like that. When someone asks you to do something or just makes small talk with you, do you ever explain what YOUR feeling like if they ask you to go do something and you've been there before would you say 'Okay' or would you be like 'Oh I've been there before, that place is awesome let's go!' ? I'm realizing I can add more to what I'm saying than what I'm used to saying..Do you know what I mean? :D
