You're definitely not a fool! I get those feelings of paranoia too when waiting around. Especially when waiting for appointments!! Am convinced everyone knows exactly why I'm there, that they know exactly who I am and are going to tell everyone I know about it. (to make that even lovelier, I'm flat out paranoid about being late so I am always somewhere super early... and of course, anything medical is alllllways running late... and then I get paranoid that I've got the wrong date or time or that they've forgotten about me or cancelled without telling me.... etc etc)
