I don't like to lie but I don't consider myself a truth saint either so what I do is the oldest trick in the book: half truths even though I prefer to call them techincal truths. The most recent example of a not so techincal truth I told someone was back in 2011 when my school exames were very mediocre (I still passed easily but the grades were somewhat weak) so, instead of telling my mom the actual grades, I told her the grade final grade. Now, I didn't really say that those numbers were what I got for the exam, I just said those numbers were what I got.
