Peter: When did you last time see Eric?
Paul: I think about a month ago
Peter: Me too...
Peter: At Brenda's birthday
Paul: That's strange
Paul: He never skipped trainings
Peter: First I thought he was sick 
Peter: I even sent him a message to see if he was ok
Peter: "I'm fine, mate"
Peter: This is what he wrote
Peter: Nothing more
Paul: Maybe he's having difficult time
Paul: But I have no idea why would that be
Peter: Maybe we should visit him
Peter: He was never really close to me but I'm worried
Peter and Paul saw Eric last time a month ago at Brenda's birthday. Peter sent him a message, but Eric was laconic.
