"And when He had sent the multitudes away, He went up into a mountain apart to pray: and when the evening was come, He was there alone." (Matt. 14:23)
A true walk with God necessitates a certain degree of aloneness. A time where we get alone with God for the purpose of prayer. I honestly don't think that a Christian could be a spiritually minded Christian without a season of aloneness. So many times we like to be with family and friends, even work and neglect time alone with the Lord. If we say we are too busy for this, then we are too busy and need to reprioritize.
