Dear Anon,
Please remember to stop by the tourism center in Las Pegasus for a complimentary cloudwalking spell (and emergency parachute), and inoculations against most fluid-born pony diseases that may not be up to date.
This advice is for both yourself AND Twilight.
Oh and if you or Spike hybridize with anypony, be forewarned that there are very strict foal wellfare laws in place. Use protection!
Your friend,
CelestiaPS. Luna gives her blessing for you to... Well I shall paraphrase as 'Get some much-needed practice at a canter before trying for a gallop'.
