They yell at each other, and laugh with each other.
They chase each other in circles, and dance like loons around the lounge. They won’t eat dinner unless they’re sitting side by side, and steal food off each other’s plates.
They climb into bed together (even though they know they’ll get told off) and keep each other up until silly o’clock, singing songs and giggling hysterically. They wake up and immediately start calling for each other.
They drive each other nuts, and love each other to bits…
