It may be, but it should not. You can go alone for the purpose of making friends with yourself. I this is why, I think, lots of people prefer not to be alone: they are afraid of reflection. Or, god forbid, being alone in silence, without some loud music to deafen the voices you might hear.
I see being alone as a kind of meditation.
I'm not afraid of reflection or silence, not at all. Just doing things isn't fun alone and after a couple times doing something alone I decide staying in is more entertaining.
