3. a few months after elizabeth was born jack retired and opened a bait & tackle shop with a couple of fishing buddies.
4. when charlie was 15 the family moved to canada for him to be in a better hockey program. when he was 18, he became the youngest player in the NHL draft that year. two years later his team won the stanley cup.
5. shortly after the big win charlie met a woman sports reporter. he likes dogs, she like cats. he drinks coffee, she drinks tea. he vacations in the mountains, she vacations at the beach. they have heated discussions about everything from penalties in hockey to the best bait to use for catching certain fish. the wedding is next spring.
