Go菜鸟关于switch问题求指点！

菜鸟求教，一个简单无限循环代码，但为什么输入bye，却无法结束呢？

package main

import( "bufio" "fmt" "os" "strings" )

func main(){

inputReader := bufio.NewReader(os.Stdin)
fmt.Println("Please input your name:")
input,err := inputReader.ReadString('\n')
if err!=nil{
    fmt.Printf("An error occurred :%s\n", err)
    os.Exit(1)
}else{
    name := input[:len(input)-1]
    fmt.Printf("hello,%s What can i do for you!", name)
}
for {
    input,err = inputReader.ReadString('\n')
    if err!=nil{
        fmt.Printf("An error occurred :%s\n", err)
        continue
    }
    input = input[:len(input)-1]
    input = strings.ToLower(input)
    switch input{
        case "":
            continue
        case "bye":
            fmt.Println("bye!")
            os.Exit(0)
        default:
            fmt.Printf("Sorry,I didn't catch you.")        
    }
}

}
