Some assembly

I'm placid.
Flaccid.
Passive.
Mix a base with acid.
You get me. The right now version.
I also come with irrational
And overboard.
I come with "people don't like you because insert reason."
I come with ignored.
I come with trying too hard.
I come with bored.
Average.
Hassle.
Baggage.
Fragile. Handle with care.
Handle.
Don't touch me.
I come with
Get off me.
I come with, I need some time to think.
I come with I wish I knew what to say.
I come with a ship
I came here to sink.
Some assembly required.
