Its not that they dont feel pain , but its in their instinct not to show it . <| sep |> Heh the only time i have ever jumped is while tripping P <| sep |> I have a friend who does this . For instance , her boyfriend and her broke up two weeks ago . Today she told me she was so upset about that she lost 80 pounds since . 80 pounds in 2 weeks . Later that SAME day she complained to the whole group of friends that she couldn ' t find any bras in stores to fit her DD boobs . Like . Okay I know its the internet but we HAVE met in person . I grew up with her . She is slightly underweight with an average sized chest . I don ' t understand how she could lie about her PHYSICAL BODY we can all see in the pictures she posts online .
