I was being sarcastic . but maybe he was just trendy <| sep |> Walking with your nose buried in your phone . I appreciate you may occasionally need to check a map , so just move out the way . Vaping while walking on busy pavements , or narrow alleys . Yes , it ' s better than a face full of smoke but be aware of how much vapour is given out . <| sep |> had the same problem with a water proof speaker on vacation . stuck it on my forehead for like 2 mins in the pool swam around took it off and i had a huge hickey all week everyone who saw me would give me a hand gesture of making a circle on their head with a pop noise from there tongue <| sep |> What isn ' t a good thing , is interviewing with a company without having any intention of working for them . Another bad idea leading to burned bridges is renege on signed contract . That said , these situations happen from time to time , people sign contract , then accept offer from other company . It ' s not ideal , some bridges are bound to be burned , but it ' s not end of the world . Still , I personally would cancel the interview with explanation that I already signed contract with another company . That ' s my personal opinion , you don ' t need to listen to me . Think about it this way . You ' re right now counting on company A still being interested in you when you eventually join them this december . But what if they suddenly decided they don ' t like you as much as other candidate and would rescind the offer ? You wouldn ' t be too happy about it , would you ?
