I'm going to show myself up here by admitting that punctuation has always been a bit of hit and miss for me.
I'm not the cleverest person but then I'm not stupid. I did learn it at school but it seems to have gone out of the window with a lot of other things such as adverbs and prepositions etc.
I'm sure that YP at https://beefgravy.blogspot.com/ must despair at people like me as he was a teacher. lol
I write as it comes into my head and splash a few comma's and full stops where I think they look okay.
So, sorry if you have to read some stuff a couple of times to make sense of it but that's me. lol
