Absolutely right. I hate doing it and want to get rid of it because :

• The actual conversations NEVER go like the script so it is just useless
• This habit drains a lot of energy and time from me
• It kind of makes me detached from reality. I can't feel or understand the other person like I would if I were normal
• It derails my train of thoughts too much. Like in the middle of thinking or working, I get distracted into mapping out a conversation I'll never have

I tried a lot. I stop myself as soon as I realize I'm doing it, but the habit never dies.

Anybody got any tips to deal with this thing?
