I grew up on make-believe so this is just the next natural progression. Only this time my make-believe session is controlled by a power-tripping guy wearing a Doritos laden shirt in his basement with a giant "DM" gold badge on his mantel that he strokes with a diaper every night.
If I can't make it several times, I'll excuse myself from the campaign with a suitable exit. There's no awkwardness or feeling of disappointment.
