If you want to initiate small talk don't leave it too long, start with a greeting if you haven't already, ask 'how's it going' or 'how are you doing', come up with further questions if they give a complex response otherwise provide an anecdote about something you're up to (come up with these when you do the thing otherwise your mind will go blank when you go to bring something up).
