Take A Seat

Find a place where you are comfortable and sit down. You can kneel or cross your legs also. Whatever feels comfortable for you. 

Find or create a place in your home where you can comfortably sit with a good book without interruptions. 

There should be no television or computer near the chair to minimize distractions, and no music or noisy family members/roommates.

... before you talk about something important.

Invite your partner to sit down with you, without distractions, and let them know that you want to talk to them. Let them know how you feel and that you find it important to feel emotionally safe with them.
