please check the error in the following sentences-:
1)I think you were not aware of your dad's gun, thats why you flunked your final examination.
2)I cannot talk to you right now because I'm having dinner. ...

Remember that sentences start with a capital letter and end with a full stop.
The comma is necessary after "gun", "right" and "now" are two seperate words.
Sentence number 1 is grammatical, but I don't understand the reference to a gun.
