Grand siblings

When you have siblings with an 18+ year difference.

John: “My dad called me the other day and told me I’m about to have twin sisters. He’s 60 and I’m damn near 35!”
Jim: “You got grand siblings that’s crazy.”

Eldest sibling syndrome

Eldest sibling syndrome or E.S.S is When you are the eldest amongst your siblings so you automatically fall into the cycle of having to use things until they are disintegrating because you can't ask for new ones.

Whereas on the other hand any younger sibling can ask for whatever and get it instantaneously because they are not the eldest.

Examples of this include tattered clothes and using things until they break.

Person 1: Dude. Your underwear is literally hanging by the elastics. Why don't you get new ones?

Person 2: Oh you know why. Ask my little brother.

Person 1: No wait. Don't tell me you have Eldest Sibling Syndrome!?
Person 2: It's gotten worse
