What I’m doing

Junghwan has been playing a swimming in Seo-Gu Youth Center 서구청소년문화회관 every weekend for 7 months.
Every last weekend, shuttle bus does not drive so I have to pick him up there.
The time when he play and enjoy swimming for 2 hours is my private free time alone. Spending time by myself is not common circumstance for me and I don’t have any idea or plan to spend this free time.
Somebody tell me how can I waste time or what do I do now?
