Hi,

I think I need some advice on my below sentence. When talking to a friend, I want to imply that whatever I'm saying is based on my observation;

1) On my observation, my sister does not want to have a love life.
2) In my observation, my sister does not want to have a love life .

Please advise, thank you.
