Making a doodle has its own fun. While enjoying coffee at a cafe by myself I tried to make a doodle, and indeed this activity is very fun. It would not be a mistake to say that drawing a doodle is the best friend to get rid of the feeling when sitting alone.
From every line I make, I feel like inviting the mind to speak with pen ink. What we are talking about is recorded on paper in the form of figures that may not mean anything. But I do not think much about this issue, because what I'm doing is just for fun.
Like I said, drinking coffee while drawing a doodle or otherwise is a very nice job. I think it's a kind of alternative therapy for people who are too complicated with their own thoughts.
