This is a conversation (give or take a few words) I had with my good friend Catherine, after I had a particularly difficult day with Angel.
E: When is the terrible threes gonna end?
C:I wish I could say at 4... Problem is then comes the terrible four, five, etc... just experimenting the Terrible Teens now, will keep ya posted, haha!
E: You mean it never stops?
C: Well the good news is: it never stops indeed but it keeps evolving in nature, impact and consequences, so you never get bored!
