In macro forbid calling another macro

[zbor]

I have a macro in a sheet that runs on a cell change:

Private Sub Worksheet_Change(ByVal Target As Range)
 On Error Resume Next
 If Target.Address = "$C$9" Then etc...

I saw that other macro call this function although it doesn't use this cell.

If I know that some other macro won't use this cell can I force macro to skip running this one?
