A question mark has got a full stop on the bottom sweets, so don't worry about an extra one. lol
Bless him! He worries about the oddest things.

Personology sounds interesting Chloe, and I think it's a great idea to start with something you find easy to understand and then build up to something more complicated.
Tarot is a really great skill to have, but it can get very complicated if you go for big readings using lots of cards, especially if they cross the questioner and each other. Some readings can take ages.
I must admit I usually stick to the simpler ones that use about 7-10 cards, tell simple past and present, and concentrate mostly on the future readings.
After all the questioner knows about their past and has a pretty good idea about their present. They came for their future reading, so you owe it to them to cut straight to the info they want.

Good luck with your personology Chloe, maybe I could get you to give me a reading when you're more comfortable with the skill? I love having my future divined.
