I like chocolate ice cream but i like strawberry better. I understand all letters at the beginning of a sentence start with capital letters. Could you use within the sentence a small i to denote you have already identified yourself as I, why repeat in in every sentence? pljames
In standard English, wherever "I" refers to the person speaking, it begins with a capital letter.
In personal text messages and emails, of course, many people use a lower-case "i".
All the best,
