As for weekends, these are often reserved for quality time with my other half and our little man.
In short, I may not have lost friends since becoming a dad, but I have lost touch with many. Interactions are less frequent now, as are outings. Especially with those where our paths are no longer aligned. It feels similar to leaving high school, and you begin to evolve as a person — the same happens in this case — it's a natural progression, but you aren't exactly 'missing out.'
