I know both “be going to do sth” and “be about to do sth” are used so often in English, but I seldom notice their differences, and I made a mistake , like :
" I am going to do the babysitting ",
“Ok, then see you later”
“Not this moment, later today”
I think , that "be going to do " has a meaning of doing something soon(maybe very soon), but I do feel confused about the “time” . Is it right that “be about to do sth” means a closer time (compared with “be going to do sth”) ?
