I never had a nick name at school
The thing is – back in the day kids had to have a nickname as there were probably at least 3 or 4 kids in the same class and a fair few more in the school who all had the same name as them.
I did a bit of work in schools a few years back and out of a year group of 40 no two kids shared the same first name (and nobody had weird or weirdly spelled names either). Just the other week I worked with nearly 100 kids from 4 schools and there were hardly any duplicates then too. When I was that age you were lucky if you could manage to get 4 people round a table without some of them having the same name. In my geography class we had a table where everyone was called Andrew.
Amongst the kids I was working with it didn’t seem like anyone had a nickname – not just because of there being no repetition of names but because they all had names that were short and easy to say in conversation to begin with – there wasn’t even the need to shorten them.
