Our reading
An editorial interpretation.
The speaker says they had let themselves forget that they were different, until someone reminded them. The word 'thoughtfully' is plainly ironic, turning a supposed kindness into a sting and suggesting the reminder was unwelcome and pointed rather than considerate.
