Английский. У меня здесь есть ошибки? Какие? подскажите, пожалуйста

What exactly do you want to do with this skill? :D Can you give an example? :D It seems to me that there are a lot of situations, when a person manipulates someone although he/she could simply ask someone to do something directly without manipulating :D
No, even with the best will in the world I won't be able to do it.
I don't know if you are a good story teller but anyway some of your stories make me smile. In fact, I do always smile reading funny messages from my friends or from people on this site, and, you know, it looks very stupid when I do it sitting in a metro wagon. Because when I begin smiling broadly in a metro wagon, people around me begin staring at me in a very strange way with sooo frowning faces that they kill my mood :P (it seems to me that I'm the only one who has this stupid habit :P) Have you ever had the same situation? :) (Хотя "Have you ever had the situation like that?" тоже вполне корректно:).)

it seems to me there are a lot of situataion -> People often manipulate when they simply can ask.

in fact -> actually

it's very stupid -> it looks stupid или it feels stupd

people there stare at me -> people start staring at me
