@iceteaslayer Keeping in mind that he didn't have any friends it all sounds logically grounded. The guy merely didn't have anyone to tell lies to. Well it's just the way how I can explain this...
If the numbers count lies, then she told three lies in their conversation. I believe they are "you weren't looking well, so I was worried" (she wasn't worried) "a person's worth isn't measured by numbers" (if numbers count lies, then it gives an insight towards that person's worth through their honesty) and "I think you have plenty of charm, anyways" (she doesn't think that he has charm).
