This is Memorial Day weekend here in the US. Established in 1868, May 30 was designated as a day to remember those who had died in the War, and decorate their graves with flowers or other remembrances; it specifically stated that organized remembrances should not be held.
Of course, since them, parades honoring veterans have become commonplace for Memorial Day. And we now use the day to remember all of those who have passed before us, in addition to those who gave their lives defending freedom everywhere.
And, lastly, Memorial Day is enjoyed as the start of summer: We gather with family and friends, barbecue, or even just toast marshmallows, and look forward to 3 months of lazy, hot weekends. As for me, I'm thankful that we no longer have to wear bathing costumes such as this (hubby's grandmother, presumably with one of her nieces, at about age 30, around 1910 or 1911).
Happy Memroial Day, everyone!
