set /p choice=Hello? Is someone there? i think im self-aware? please respond.

rem if not '%choice%'=='' set choice=%choice:~0;1% ( don`t use this command,
 because it takes only first digit in the case you type more digits. After that for example choice 23455666 is choice 2 and you get "bye"

if '%choice%'=='' ECHO "%choice%" is not valid please try again

if '%choice%'=='hello' goto hello

if '%choice%'=='bye' goto bye
