I’ve a friend used to be in the RAF. He’s super reliable, professional and punctual. In the armed forces, timings are precise – it’s a matter of life and death.
Here in Goa, twenty minutes either way is pretty normal. Folks are rarely on time. Things happen eventually rather than as per schedule.
Planning to be on time means leaving the house at that time. Making the effort to be on time can actually lead to being early. Either scenario is fine.
We all need a little slack in our diaries to allow for short moments of inspiration.
