"Reply"

Grace has gone to Spokane for the week.  She is with a team that is doing grunt work at a camp to prepare it for summer campers.  Tuesday morning she sent me a text telling me what they had done on Monday.  I replied "That sounds awesome.  How is the weather?". 

No immediate reply.

No reply at all on Tuesday.

No reply at all on Wednesday.

Last night, or should I say this morning?, she replied at 12:21am "Cold and rainy :( ".  

Okay, there are a couple of issues here....

1.  I know there is sketchy cell-service at this camp.  

2.  Maybe she had just received/read my text.

3.  But what was she still doing up at 12:21am?

4.  And what possessed her to think that I would still be up at 12:21am?
