Happily Ever After

Why does Parshas Ki Savo bring a long list of curses on someone who kept the mitzvos, only because he didn't serve Hashem with simcha? If the mitzvos got done, what difference does the mood make? Rav Simcha Zissel of Kelm finds a hint in where you place a comma in the pasuk. It speaks to anyone who does everything right and still feels flat about it.A master carpenter, ready to retire after twenty years, gives in and agrees to build one last house for the contractor who owes him everything. His heart isn't in it, and on the final day he finds out why that mattered.
