Let me go on the record and say that I think having two young(er) women in the family is perfectly wonderful. I always knew it would be, because we determined to raise our children in such a way that we would not have typical teenager problems. With God's help, of course, and by his grace. Not that we don't have hormones, mind you, and it's not like we get along perfectly all the time.
The word "teenager" is a recent addition to our English language. See here for a brief explanation. I don't have a problem with people age 13-19, just with the connotation of "teenager". When we play Apples to Apples, my family has to have a discard pile for all the cards with people's names that our kids (and us old fogies) aren't familiar with. Like Brad Pitt. Who's Brad Pitt?? Maybe that's one of the reasons I still like my kids? I think that means we aren't bowing to the popular culture mentioned in this Way of Life article.
I now have two between 13 and 19. It has been such a joy to see them pursue their interests for God's glory, develop the talents he has given them, and grow in character. Amy washed all the supper dishes last night without being asked (there were a ton of them), and without even sighing within my hearing. On her birthday! I'd say that's a good start into the teen years. I'm so blessed to have my terrific teenagers!
