Answer the question about text:

So last night , I get a text message from one of my old friends that I have n't really talked to in a very long time . My friend , Amanda , and her other friend , Jesse , wanted to do something because they usually do n't stay at school on the weekends and had nothing to do last night . I suggested that we should find a party to go to , and they were up for that idea .

What may be the reason why they heard from their friend ?
They had nothing else to do .
