If someone was born in August of 2006, that means that when they were at school their classmates were born between September 2005 - August 2006.
Anyone born after August 2006, was a year group below them; anyone born before September 2004, was a year group above them.
Growing up, a person born in August 2006, would have been socialised with their age mates ie those in their year group. They would have done GCSEs/A-levels at the same time; gone to university at the same time (unless they didn’t go or took a gap year); would have taken part in the same championships and competitions due to the same age etc. This means they would have much in common.
When someone born in August 2006, was at school and in say, Year 13, for example, they would have likely thought they had much more in common with other Year 13s than someone in Year 12, even if that Year 12 was born in September 2006 (so only a few weeks after them).
This is as such person, even though a few weeks younger, would have been behind in terms of a year of education; would not be eligible for the same championships or competitions if they were based on year group etc.
All of this leads people to strongly identify with their academic age mates.
So, I wonder how this functions in university. Imagine if someone took a gap year and so the majority of the students in their cohort were not their age mates so a year group below, even if only a few weeks or months younger, they would not be their age mates. So, would this mean that such a person would profoundly find it difficult to relate to or understand such people because they weren’t part of the same academic year group?
How hard do you find it to relate to people who are not your age mates?
