Having to lie to people I'm close with. Most of the time it's small and it's in order to not hurt anyone's feelings. They just build up over time and it can be heavy. One of the big lies is that I'm not really religious even though my parents think I am. I know many people will say that I should be honest with them, but hear me out. If my parents truly believe that by following their rules they will get to heaven and that by turning away from the religion I won't, why would I shatter their worlds by being truthful. As long as it doesn't seriously impose on my life in a negative way, I'll take that one to the grave for their peace of mind. Hiding enough things like this in order to spare loved ones grief, is hard.
