Agree with nbwood.
try the backyard first.
I dunno why it would happen, but it IS possible that you may not like the outdoors.
Personally I cannot see how ANYONE could NOT like the outdoors.
I started camping in my teens, now into late 50's and STILL camping. :D :D :D :D :D
Over the years have done all types.
Started with tent, then wind up camper, poptop caravan, hard top caravan, and now stillhave a caravan with all the extra goodies like portable fireplace, and cooking plates etc.
After your first time at home, try camping where ther are other campers.
You will find they are friendly, (at least most are), and helpful.
Tricky and ozzy have given you some good tips.
You will overpack to start with, but you will soon get rid of the excess.
You will also forget things, some needless, some important.
Have fun camping, and maybe I will see you somewhere in the "bush"
