Amicus Unus Aptus
Aptus amicus adest unus tibi; parce secundum
Quaerere; vix aeque tertius aptus erit.
Source: François Oudin (1673-1752), Silva Distichorum, 138. Meter: Elegiac. Note the idiomatic use of parce with an infinitive: parce quaerere, "spare to look," i.e. "don't go looking, "refrain from looking."
One friend nearby you (amicus unus adest) is appropriate (aptus); refrain from seeking a second (parce quaerere secundum); a third friend (tertius) will scarcely be (vix erit) appropriate in the same degree (aeque aptus).
