“But what else does it mean ‘that you are familiar with them’?” I am not surprised to see them; I should on being asked, say that I s[ay|ee] them every day that I have sat in them 100ds of times. I could describe on what occasions they were used & tell you a lot about them. All the experiences wi[th|ch] go along with saying these things & the experience of doing so we can call experiences of familiarity.
