Likely around 5 am . Prime stethoscope thieving time . Anyhow , this has made me think of what I would do if I found someone wearing my stethoscope . And it reminds me of a story from undergrad . When I lived at 3 Aberdeen St during my time at Queen 's , we would often have people come up to our door asking for bottles , or donations to vague charities , or sometimes they would just ask if " Johnny " was home . These young males would be carrying an empty duffle bag and have an old mountain bike ditched on the lawn .

Answer: None of the above choices .His stethoscope is very old .Someone stole his stethoscope .He stole a stethoscope once .
