i do ;-)
i have to lie a lot really, guys that just don't want to leave me alone, my father is always on my case, and my mother always wants to know where i'm hanging out! sooo....
i have a simple solution to solve the problem of remembering what you told who, and when, (this works for me anyway)
i simply put a reminder on my mobile, that reminds me every now and then of what i told who. this works great, nobody will read through my daily reminders and if they do, it is all written in this freaky code, that works wonderfully, so my reminders doesn't make any sence to anybody else. ofcourse i read through these every so often, (i call it briefing myself) and a good memory is very helpful aswell!
it is not like i lie cause i love to, it is merely because they ask me questions that i cannot give a true answer to, like my dad will ask me: how much have you saved this month? what has it got to do with him!!
i guess that makes me a very distrustful virgo, but i'm not always like that, and i will not lie to my friends, unless it is to spare their feelings.
