Let me preface this by saying, I love planners. I always have two on hand. At work, I use a Google calendar, but I would rather write everything down twice than do without my pink Day Designer planner.
After having dinner with a sweet friend of mine yesterday, I realized that there are some things worth writing in pen.
Girlfriend dates are so so important to have! Ones where you can literally talk about anything and everything over a glass of wine (or two) and a mani-pedi. These are worth writing in pen.
Get togethers with friends that you haven't seen in a good month or two, but you pick up like you just saw each other yesterday. These are worth writing in pen.
Dinners where you talk about the hard things: family drama, relationships, wedding planning/future planning (because it can be STRESSFUL), and religion. These are worth writing in pen.
