My parents, and a lot of their generation (late 60s) use their initials in their signature, for instance Dad’s is WRTSmith and Mum’s is MaryJSmith. However most of my generation (30/40s)such as me and my sister use just our first and last name, eg Emma Smith.
Is this just my family/friends? Not that it matters, i’m Just musing/bored.
( all names have been changed/made up obviously, but the format is what i’m On about)
