Here are some things you're needed for:
1. Cash (bus fares, lunch card at school, mobile phone top-up)
2. Emergency signatures (to give your under-18 permission for something he/she wants to do)
3. Frequent lifts
4. A well-stocked fridge
6. Clean clothes
7. An encyclopaedic knowledge of the whereabouts of socks, phone, vital bits of paper
8. A wake-up call when he/she has overslept
9. Random urgent shopping (tights, deodorant, shampoo...)
10. Polite reminders about anything he/she has forgotten
Here are some things you're not needed for:
1. Conversation at the wrong time (too early in the morning, before tea, when there's a good film on)
2. Any attempt to hoover his/her room
3. Any suggestions about going to bed because it's late and there's school tomorrow
4. Polite reminders about coursework
5. Expressions of surprise at choice of clothes/hair colour/ piercings
6. Clearing up (because there's nothing wrong with an open carton of milk left out by the cooker)
7. Descriptions of how things were when you were young
8. Text messages expressing anxiety about his/her whereabouts
9. Suggestions about quicker or more usual ways of doing something practical
10. Reminders about anything he/she has already remembered
Don't, whatever you do, get these lists muddled. Or you'll get the sagging shoulders of one who has been driven beyond what any reasonable person should have to put up with.
You have been warned.
Does this ring true for you? Any other times you can think of when you're needed/not needed?
