Dear Katie,
I thought Id send you a quick email to remind you what to take on our hike this weekend!
First, it may get cold, so make sure you take some 1 ) warm clothes. I know your 2) rucksack is quite small, so if you dont have enough space, you can put some things in mine. I will bring the 3) first aid kit in case we have any small accidents, but can you bring the 4) insect repellent as there will probably be a lot of mosquitoes at night. Oh, yes, please take some 5) sunscreen, too, so you dont get burnt. Dont forget to bring a 6) pen knife too, as they come in handy for all sorts of things. My fathers bringing a 7) map of the area, so we wont get lost!
Well, see you tomorrow. I cant wait.
Love,
Emma
