Why, why, why would she do that? I mean, it's her hobby, with that much importance for her. Don't you think she should have some me time apart from her family time?
Because her husbands always busy and her kids always at school or doing extra lessons and its a rare opportunity for all three to spend time together. Her lessons are obviously a regular thing so its not like she'll be missing out completely but soon her kid will be grown and have his own life and she'll regret missing these little opportunities. I'm not saying she can't have time to herself I'm just saying she shouldn't miss out on these small but important moments. My parents were always working or at church and so sometimes it feels like they (and I) missed out on things. Memories that will be important one day.
or perhaps she should take her husband along.
Woman skip your lesson and take this rare opportunity to spend time with your family! What are you doing!?
