When someone says "I came to realise...", I know it can mean he realised it gradually.
Can it mean one day he suddenly realised something? For example,
One week later, I came to realise that I missed my appointment.
If this is wrong, can I ask how to express the meaning of I realised something very late?
For example, normally people realise they missed an appointment on the day or next day, but I realised it one week later.
