I finally got around to writing my christmas thank you letters! It's only taken me almost-a-month! I bought some pretty notecards on the way home at the station last night to make the job a bit more fun, and then sat at my mum's desk (she must be the only person with no computer on her desk, but a complete 1930s desk set with inkwell, and a vintage phone!
The art of sending thank you letters, or more likely the duty(!) was definitely drummed in early by my parents, but I still try and send a few out if I get gifts, especially if they came by post so I haven't been able to thank the sender in person.
