This has been bugging me for awhile. I'm trying to write a story in the past tense, but sometimes I get my tenses confused.<br/><br/>Can someone tell me the difference between:<br/><br/>I just realized I've hardly touched the book <br/><br/>and<br/><br/>I just realize I hardly touched the book.<br/><br/>When writing a story in the past tense, when do you use has/had/have.<br/><br/>Thanks!
