Choccy Milk
Siblings get into fights all the time. That’s just a part of the growing process, and by the time you guys are old enough, you’ll look back at your sibling rivalry and think about just how ridiculous it was. For the OP, one problem they had with their late brother was drinking chocolate milk. It got so bad that the two had to have separate cups for their chocolate-drinking ritual.
When the brother passed away, the OP knew the perfect way to send their never-ending love. They got the glass that the brother used to drink chocolate milk back in their childhood days. It seems silly, but we guarantee this guy gets choked up whenever he takes a hard look at his brother’s old choccy milk glass.
