think if I sent the poo-pooEnvelope to wrong person by mistake

I have been consulting my doctor lately, since I have got some not highly dangerous, but uncomfortable& complicated health issues to discuss. we agreed that I even should give him some poo-pooSamples( how fancy:-/)for certainty..my doctor is a really funny&kind man;so we were roaring of laughter when talking the practical aspects of a poo-pooTest: "ha ha hoo haa ha;no my fiend, you don t have to produce all the six samples of poo here and now, you can do it at home ha ha ho hohaa/this is so hilarious:D"( now I know where I am gonna spend this weekend:in the toalet:-/)..later on I am supposed to leave those samples to health centre and place them on the tiny wagon in the corridor: so I started to fantasize at once: think if I send the poopEnvelopes to my grandma by mistake or think if someone passes by the wagon in health centre: " bloody h_ll, the jobApplication-a envelope/I need a envelope:hah,there is one on the wagon;I borrow one, there is nobody around who can see me right now anyhow....and bla bla bla xoxo xoxo on friday
