LOL. I know I wouldn't. I don't even notice it when my closest friend in college had been yelling my name for 15 minutes until she stood right in front of me and glared at me.
heh, i'm like that too... my friend can be standing right beside me in the toilet and all i care about is concentrating on washing my hand and didn't notice she's tehre... but then, if Tom Cruise really walks by you and u didn't notice, that would have been a pity :D
Did I ever tell you that I am probably the worst person to meet on the streets or any public places for that matter (especially if you happen to know me and happen to wave and say "hi" or something along those lines)? Tom Cruise can walk by me and I wouldn't even notice.
I tend to be pretty mentally-disoriented when I'm outside. My mind keeps floating away to nowhere.
