How can I keep my girlfriend busy?

My friend (22) is currently with her half sister (50) and takes little care of her son (5). But she is bored when he is sleeping and I would like to keep her busy. Unfortunately she doesn't have a laptop because otherwise I would have bought her some computer game that she could like and played it with her. Can you think of anything I could do to keep you entertained (except for calling and chatting)?

I'm grateful for any idea.

Play mobile phone games online and make phone calls during that, it's always very funny and sometimes fun to build something together. Here are a few games you could play together: Bowling King, call of Duty, Brawl Stars, Uno and much more
