my t and i laugh a lot - sometimes about morbid things (when i'm suicidal) because that's how i am. people make assumptions about my mental health based on the fact that i laugh - missing the point that just because i'm laughing doesn't mean i'm not in distress. it's my way of handling my distress because if i didn't laugh, i'd cry (if I could cry).

if you're concerned he's shorting you on time (which you are paying for), then bring it up. four minutes could have been 2 minutes on his clock - it's not uncommon for clocks to be off. however, also ask, how often does this happen? is it becoming a habit? or is it worth taking a deep breath and figuring out how to let go (in which case, discussing it with t in that vein - hey i feel this way, but i would like to let it go, how do i do that?).
