Isn't it weird that Summer Holiday AND Travis Scott are always single?

Probably because he spends most of his time on a computer and dresses like a grandpa. Maybe Summer is one of those girls that looks for bad boys.

I did play the household once but just kept them as roomies. Mostly their jobs were too intensive for any social activity to go on. Well, Summer's job is not very intense but Liberty and Travis have jobs that require a lot of time investment.
