i always lie....now i know lying probably doesn't help...but neither does tell the whole truth....shit take this situation (made up to emphasize why you shouldn't just start telling everything)

mom: were those your zigzags in your pocket?
~son commences to tell everything about how he does drugs and so fourth~
mom: WHAT?! ~lots of screamming~ i was just going to ask you where you're getting your tabacco from to roll cigarettes, but now i know why you have these papers
~mom hands down heavy punishment and kid feels stupid for ever saying anything~
