this is key, isolate the buds from the seeds & stems: smoke only the bud. surface area is the key to clean combustion - break up the buds with a grinder (you can probably buy one with the bowl), scissors, or coffee grinder (new one). Get the pipe if you've never rolled a joint before. It might take a minute to feel the buzz; don't rush, just relax & listen to some cool music. the mood will set itself.... if all goes to plan, it will heighten the pleasure for you both.
If you have to watch someone who is mentally deficient I wouldn't recommend getting blowed for your first time. You're going to be incredibly sleepy and feel somewhat disconnected. Your vision gets "cloudy" if you will (like when you get up too fast from your seat or bed--vertigo). That's the best way I can describe my first time getting high. The more you smoke the more that tones down though, and it just gets more and more awesome...
