riddle - You might find me in a costly lawsuit. What am I?

Pros:

1. I always let my friends go first.



2. To some of my groups of friends, I mean every.


3. No matter who I am around, I always have an effect on them.


4. I am strong-willed; none of my friends can change me.


5. I have a magnetic personality, so I am always near friends.

Cons:

1. I'm short.



2. I do not like to be alone- I am clingy.


3. I never accept some groups of my friends for who they are, and instead, I try to change them, and always succeed.


4. I'm bossy- usually the one telling my friends when, where, how, why, and under what circumstances things are going to happen.


5. I have 2 personalities- one is almost a teenager, and the other is in his mid twenties

Hint:

The title is a hint. Don't overlook it.

Answer

The letters ly

I always let my friends go first.

ly appears at the ends of words to make them adverbs, usually

To some of my groups of friends, I mean everything.

Thinking about the ly in the context of the word poly, meaning every

No matter who I am around, I always have an effect on them.

ly turns some words into adverbs when added to the end

I am strong-willed; none of my friends can change me.

adding suffixes to ly doesnt change it

I have a magnetic personality, so I am always near friends.

ly on it's own doesn't mean anything

I'm short.

only two letters

I do not like to be alone- I am clingy.

again, only has meaning when added onto an existing word

I never accept some groups of my friends for who they are, and instead, I try to change them, and always succeed.

adding ly changes adjectives into adverbs

I'm bossy- usually the one telling my friends when, where, how, why, and under what circumstances things are going to happen.

adverbs describe how something is happening

I have 2 personalities- one is almost a teenager, and the other is in his mid twenties

l is the 12th letter of the alphabet, y is the 25th
