computer, welcome to Using English.
Please make sure you give your threads titles that tell us what you're asking. "A" is not a useful title. You could have called it "Reverse side of our palm" or just "Palm."
Also, we hope you'll adopt good habits early and use capital letters.
Finally, many of us are women. You can start with "Hi friends" if you wish (it's nice and friendly) or you can just jump in and ask your question, but I feel insulted when questions start with "sir."
I hope you'll find this forum a good fit for your needs in learning English.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
