I came across this sentence in a novel that I am reading, which is about the life of a drug addict spent in a drug treatment facility:<br/><br/>Four or five thousand dollars a day is enough to kill a person <b><i>several times over</i></b>.<br/><br/>Is <b><i>several times ove</i></b>r the same as <b><i><u>more than</u> several times</i></b>?<br/><br/>Is it commonly used in daily-life conversation?<br/><br/>We sang the song <b><i>several times over</i></b>.<br/><br/>If you are still noisy, you have to write the sentence <b><i>three times over</i></b>.<br/><br/>I have told you <b><i>a million times over</i></b> not to touch my stuff.<br/><br/>Are the sentences above correct?<br/><br/>2. What's the difference between at one's side and on one's side?<br/><br/>He's standing <b>on/ at?</b> her side.
