Before anyone has a go I know that this is trivial.
My child has a very common name that can easily be shortened. Imagine Thomas, Daniel, Oliver.
We don’t ever shorten his name, he doesn’t like it to be, it doesn’t suit him so we stick to his full name.
I know that people will always shorten it, but when family do it for some reason it irritates me. It feels like they’re referring to someone else.
I have a long name that can be shortened and it really doesn’t bother me because I’ve always shortened it, it just doesn’t suit ds.
