Imagine you're trying to ask someone for their thoughts or opinions about something, or you're giving them an option to do something. You might use the word "should" at the beginning of the question to make it sound more polite or thoughtful.
Here's what those questions mean:
"Should you have any queries?": This is like asking, "If you have any questions, please let me know." It's a polite way to say that you're there to help if someone has questions.
"Should you have female friends?": This question is asking for someone's opinion about having female friends. It's like saying, "Do you think it's a good idea to have female friends?"
"Should you have multiple YouTube channels?": This one is asking for advice or thoughts about having more than one YouTube channel. It's like asking, "Do you think it's a good idea to have more than one YouTube channel?"
So, when you see "should" at the beginning of a question like this, think of it as a polite way to ask for someone's thoughts or to offer help. It's like opening a door and saying, "You can come in if you want to." It makes the question sound kind and thoughtful.
