Sides
Because most two-person tents will have only one way in and out, you'll have to decide who sleeps on the inside and who sleeps nearest the door.
Assembly
Most two-person tents assemble very easily; just slide a few poles into fabric sleeves, attach the rain fly, and with some models, stake it out.
Teamwork
While one member of the team is assembling the tent, the other person can keep busy cooking food, sorting gear or organizing the campsite.
Vestibule
Make best use of your two-man tent's vestibule by keeping wet, muddy or dirty items outside your living area but still otherwise protected from the elements.
Headlamp
A small LED headlamp can be very useful for reading at night without disturbing your tent partner.
Direction
Make sure to evaluate the prevailing wind direction--look at the trees to get a good hint of it--when pitching your tent; ideally, the door should open facing downwind.
