1) nicknames have varied. For a while in college I was trying for a favorite animal’s generic name, and I still really like being referred to as any animal I associate with. My favorite nickname ever tho is when very little I couldn’t easily pronounce my name, and my Gramma and Grampa used my version until they died. I DJ if I’d be cool with anyone else using it.
@Leucrotta Oh, and in case you're curious but not conversant in IPA – not judgin', I'm not either – you can plug that into http://ipa-reader.xyz/ and set the voice to the very last one (Gwyneth) to hear it. I love that site.
