Person: You know you should be more social and talk more.
*Later that day*
I walk up to the person that said it and start the 'conversation' with this:
Me: The Legio I Germanica, the German legion, was a Roman legion, possibly levied in 48 BC by Julius Caesar to fight for him in the civil war against Pompey. After the Batavian rebellion (70), the remaining men of the Germanica were added to Galba's seventh legion, which became VII Gemina. The emblem of Legio I is unknown, but it was probably Taurus, like all the other legions levied by Caesar.
There are two theories about I Germanica recruitment. The most favored is that it was raised by Julius Caesar in 48 BC to fight in the civil war against Pompey. In that case it would have fought in the Battle of Pharsalus in 48 BC. A second theory attributes its recruitment to Gaius Vibius Pansa Caetronianus, a partisan of Caesar, who died in the Battle of Forum Gallorum against Marc Antony in 43 BC. Legio I would have been recruited in that year for that campaign. However recruited, Legio I was inherited by Augustus and therefore ought to have been entitled to the cognomen 'Augusta' after distinguished service under his eyes; however, there was no Legio I Augusta. One explanation is that an event happened to prevent or take away that name.
The career of Legio I subsequent to the civil wars remains unknown for sure. It is believed to be identical to the Legio I that took part in the Spanish campaign against the Cantabrians conducted for Augustus by Marcus Agrippa and was disgraced there. Inscriptions on Spanish coins indicate that between 30 and 16 BC, some Legio I was stationed in Hispania Taraconensis, where they would have fought in the war against the Cantabrians. Dio Cassius (54.11.5) says that one legion was stripped of its title, Augusta, after suffering reverses in that campaign. The two references are believed to be to the same legion, accounting for its early missing title and emblem.
