Hi,<br/><br/><br/><br/>Are the following sentences natural to a native ear?<br/><br/><br/><br/>1. Don’t worry, it is just your eyes playing a trick on you.<br/><br/><br/><br/>2. Just for argument’s sake, if I add it back, the answer will be way too large.<br/><br/><br/><br/>3. Can I take the next two days off as a vacation? ( I wanted to put this line in my leave application)<br/><br/><br/><br/><br/><br/>Thank you,<br/><br/><br/><br/>MG.
