Theft in my neighbors house

It was on Sunday morning at 0:15 a.m or something like this when I heard some bangs but I thought that it hadn't been anything else than the rain because it had been raining a lot for the last ten hours or something so that's why I though the rain knock something after had been depositing all those hours on something. The fact is that our neighbors are really old and they're French people so they had been living here for almost their entire life but now they had gone to France with his son so they're weren't here. So I went to sleep at two o'clock or something like this thinking all these knocking noises weren't thieves but the truth is that when I woke up the following day my father told me that somebody broke all the dors of our neighbors so at that point I felt really sad with myself because I had to check if everything was okey.
