I would also stop that habit because all you need it letting it inadvertently last a bit too long and being noticed. I'm personally into maintaining eye contact with the person I am with, not rehearsing what I'm going to say next- no need to lock eyes all the time or be intense but I am with that person. Whether my husband or friend or family member. Yes. I stared at Bon Jovi in an elevator my then boyfriend and I were riding. There are exceptions!!!
