It has been entertaining so far, and a nice change from the usual stuff (Tarntawan hotel anyone?), leave it running.
I had boys who described themselfes as slim, but were too fat by my standards. When I tell them inevitable I will hear "but I'm just 55 kg (at 165 cm)". It's best to use numbers, I'm 36/72/184 (age/weight in kg/hight in cm - that's actually too fat by my standards) to avoid misunderstandings. Some day a 50 year old will come and tell he is young, because he knows a 70 year old who could be his father.
