My dear and respected teachers,

1 : "I'm a little bit impudent becuase I don't often greet my friends in private but if I ever do...appreciate it If you don't...I will never greet again"?

2 : "I execrate those people who abandon their parents when they have grown up"?

Hello teachers, check if the above statements are correct and if you have time.Please rephrase them by using excellent and more difficult words.Only if you have time otherwise just correct them, thanks in advance.

The first sentence for me is a puzzle! I can not get it.

From your second sentence I understand that parents left when they grown up...

P.S. Im not teacher

1 : "I'm a little bit impudent therefore I don't often greet my friends in private. But if I ever do greet you, appreciate it. If you don't, I will never greet you again"?

2 : I execrate those people who abandon their elderly parents.

I just love your choice words, especially impudent and execrate. They are so fancy. Of course, you could use rude instead of impudent and despise instead of execrate, but profoundness of your vocabulary is admirable.
