Ex Input:
I just got back from a vacation spending a week at the beach with my son. It was so nice to get away for a while. What is not nice is the amount of laundry I now have to do! The first thing I did was take both of our suitcases down the hall to the laundry room. I dumped out all of our dirty clothes. I sorted into 3 piles- the towels and thick items that don't have any wash restrictions. The second pile was my clothes, which many need to be hung up, but I like to use a strong smelling detergent. The third pile consisted of all of my son's clothes, as well as any delicate items, such as bathing suits that will be washed in a free and clear detergent, as my son has skin allergies. I placed one load into the washing machine, with the appropriate detergent. When it was done, I put the clothes in the dryer or hung those that cannot dry. I added a dryer sheet and started the process over with the next batch. It take time, but sorting it out is the best way to tackle the task. 
Question: When did they start washing clothes?

Ex Output:
When they got back from vacation.

Ex Input:
I don't know why , but I suspect it's because at night it's dark , and he has become used to falling back asleep , like we all do at night . During the day when it's light , he wakes up and can't put himself back to sleep yet . The other bad thing is that until now , I've let him take his afternoon nap in the swing , which is becoming a problem because I think he is fast approaching the weight limit ( I'm fairly certain the limit is 20 lbs , and he was 16 about three weeks ago ) . So pretty soon , there will be no swing to nap in . 
Question: What's a possible reason he can't put himself back to sleep during the day ?

Ex Output:

Because it's too bright .
