lost moment

Do you also experience being lost at a certain point wherein all you could do is stare at one corner in your room? If you are going to ask me, yes, a lot of times, I mean, not just a lot of time,, but most of the time. I always have this dejavu slash lost moment every now and then. I even asked myself about it but I could not even find a definite answer to the question I kept on asking. Why stress my not so good mind (LOL) for things as such. It's just normal. Isn't it? Lemme, describe to you what this so called lost moment thingy I'm referring to.

Scenario 1:
Shared very interesting topic with my boyfriend about anything under the sun when all of a sudden, he stopped and immediately tried to catch my attention to keep my focus. I mean, there I was, stared at one corner or just looked something randomly and got lost in a moment. I didn't mean it of course. I had just this crazy thingy in my brain that triggers especially, if the conversation is kinda too long and too interesting. Let me correct you on what you are thinking there, I'm still listening though but my mind is not that focus to the person who's talking in front of me.

Scenario 2:
Had a little chitchat with my best buddy at Jollibee, IT Park and all of a sudden he flicked his fingers in front of my face because he thought I'm not listening to him anymore because of the lost moment look. The "tanga mode".

When will I'm going to change,, it's kinda destructing to those people who is having a good conversation with me and just in a split of second, the interest fades. Hahayz..
