What a great thing to do!
When you're bored at work - instead of re-checking your e-mail for the tenth time, or surfing, do something that will help your kid... write her a letter.
It takes, like, 10 minutes and it will be one of the most rewarding things you will do all day. Use a big, easy-to-read font like Times 18. (Resist using a cartoon or handwriting font. They may look fun, but they're very hard to read. The easiest ones to read are serif fonts, like Times.)
You don't have to say anything profound. Just chat, let her know what's happening at work, tell her that you're proud of her, ask her what she wants to do this weekend.
A letter from you will let her know that you're thinking of her, it will give her some insight into your day and it's a great way to get your kid reading!
When you're finished your letter, actually mail it - don't just bring it home. Half the excitement is going to the mailbox and getting something that's been sent to you.
It's also a good idea to include a self-addressed, stamped envelope that your child can use to write you back. (And if you use your work address, you'll get something at your desk in a couple of days besides conference flyers and departmental invoices!)
Writing your kid a letter is one of the greatest ways to spend 10 minutes. For you, and for your kid.
Don't have a kid? Write your grandchild a letter. A neighbour. A friend's kid. Santa (don't need a stamp for that one!). Snail-mail is fun... and it's still pretty cheap (especially if you sneak your letter in to the company mailbox and let the firm pay for your postage).
