I agree. It is always those little little things that seem so
insignificant that can add up to you losing your temper totally or
getting more and more irritated with him/her everyday.
The soft (or loud) snoring at night, the sqeezing of the toothpaste
in the middle of the tube instead of from the end, not putting the
toilet seat down, leaving pieces of junk mail everywhere without
throwing them away ... the list goes on ...
Small insignificant things but they can cause marriages to fail
