And if you did, I'm going to give you the following piece of advice (my family need not listen... they went above and beyond...).
Go to the person or people who helped make your Yom Tov so nice and thank them. This could be somebody who hosted your seder This could be somebody who shared divrei Torah with you at the Yom Tov table. This could be somebody who helped arrange a Chol Homoed outing. This could be a family member who stopped in for a visit.
It could be the husband who pitched in with the heavy cleaning - the wife who cooked and cleaned with such dedication - the child who shopped or babysat the little ones.
Tell them that their efforts had a positive impact on your Pesach.
(Of course, if you did everything all by yourself, you should drop everything go get a massage.... Hey, even if you had help, go get a massage... I'll come with you!)
