My sister is an annoying 14 year old.
That can be an annoying age! lol Adolescence is usually thought of as the teen years buts physical, psychological and cultural expressions may start and end earlier. It will pass, trust me! lol
I hope it will pass. She is so moody and bratty.
Yep, the moods come with it! Adolescence is viewed as a transitional period between childhood and adulthood whose preparation is to begin an adult life. In the meantime, buy earplugs! lol
It seems to last forever. I am so over it.
Well it's actually a small period of time with multiple transitions involving education, training, employment and transitions from one lifestyle to another. It is a big change.
What age does it end? I cannot wait.
Well it can vary by country and by function. I would hope it would end by 16 or so. Best of luck to you! lol
Thanks for the info!
