Spanish speakers often cushion a strong view with a handful of small words. They don't change the opinion — they change how it lands.

Softener	Meaning	Example
un poco	a bit	La peli es un poco larga.
algo	somewhat	El hotel es algo caro.
¿no? / ¿verdad?	right? isn't it?	Es caro, ¿no?
yo qué sé	I dunno	Yo qué sé, a mí me gusta.
mira…	look…	Mira, yo lo veo de otra manera.
la verdad	honestly	La verdad, no me gustó el final.

• Un poco before an adjective never changes: un poco larga, un poco caros. Without the un, poco means not very: poco interesante — not very interesting.
• ¿No? at the end of a statement invites the other person in.
• Yo qué sé takes the weight off whatever follows — fine among friends, too vague (and a touch dismissive) for a meeting.
