options: m : really ? i have no idea that i do n't look well . it seems that i need some rest . m : yeah , i know that i look tired . i 'm suffering from jet lag . m : you mean there 's a faster bus ? i did n't know . maybe i will try next time , as you said . this time 's 16 hours is really uncomfortable . m : you 're right , environment is so important that i must pay more attention to . i took a plane for some time reason , but i will take a bus next time .
article: f : hey . welcome to berlin . it 's great to see you again . m : yeah , good to see you , too . have you been waiting here at the station long ? f : only 15 minutes . but let 's get out of this cold and go to my apartment . how are you feeling after that long bus ride ? m : ah , it was n't too bad . it was only 19 hours . f : that 's crazy . you could have flown here from london , for 60 euros and it would only have taken an hour and a half . was it really worth all that time just to save a bit of money ? m : well , it was a pretty uncomfortable ride . to be honest , the bus was starting to smell toward the end of it . and there was a man next to me , who was breathing really loudly while he was sleeping . but the reason i took the bus was because it 's more environmentally friendly than flying . f : i think it 's great we want to help the environment . but you look so tired right now . i just think you should be a little more careful with your health .
