No matter what happens, a parent will always love their children. That said, sometimes, parents can be angry, annoyed, or just plain sick of their kids. Here's how you can help your parents rise above those moments.

[edit] Steps

Start by waking up early to do chores or make breakfast. Coffee is good too. Your parents might get a little annoyed if you sleep in until noon, but don't wake up too early. They might also be annoyed with having an early bird wake them up all the time.
Always do what your parents tell you to, don't back talk, or refuse. They might be very upset with you, and if you do whatever they told you to, you won't have to worry about it later.
Hug/kiss your parents often. Tell them you love them and have some special cutsie little secret handshake with them. This will make them feel wanted, and they will love you even more.
Don't stay in your pajamas all day! Get up in the morning and get dressed! Your parents get really annoyed/frustrated if you laze around the house all day long.

[edit] Tips

Always talk in your normal voice to your parents, not some annoying voice that will drive them mad.
Never take a tone, roll you eyes or any of that stuff. Parents hate that.
