。
I do have a few friends.
Literal
Friends [topic-は] few exist.
A minimal sentence — 少しいる states the fact neutrally: 'there are a few [friends].' Without しか~ない (which would add a 'only, and it's not enough' nuance), the tone is matter-of-fact rather than lamenting. A clean illustration of how Japanese particles carry the speaker's attitude as much as the literal numbers.
