One jerk was double-timing both my friends (mind you, they were
good friends!)
After my friends found out, one broke up with him; another stayed
on the relationship.
After some time, the friend who stayed on discovered that that guy
has a steady girlfriend of 2 years!
Turns out that he's triple-timing! What a jerk!
Needless to say, my 2 friends are not talking to each other
anymore...
