OT:Backyard rescue this morning

Adam came in sort of laughing this morning from work. I was asleep and I heard him chuckling to himself. He said that our neighbors 4 yr old daughter Hailey (not sure why he was chuckling cause its not funny at all)anyway Hailey had slipped out of her house sometime this morning while we were all asleep. Her dad is in the army and leaves out early. Her mom was still asleep. Adam got home about 8am or so. Not sure how long she'd been out. She had opened both of our back yard gates. We have one gate on each side of the house. The dogs were out. What scares me the most is we have a pool back there. I know she can climb the ladder cause we were all in it the other night. Its almost over my head in places and she's alittle squirt. She doesn't even look 4. Adam said she was crying when he got home. I guess she realized that she was alone out there and we weren't outside. She told him she just wanted to swing. Adam was talking about putting chains on our gates and padlocks. I don't want to do that, we shouldn't have to. I love her to pieces and her parents are sweet ppl. Adam took her home this morning and woke Tiffany up and when she realized Adam had Hailey she started bawling. She's 8 months pregnant and I'm sure this scared the stuffing out of her, it would have me. Allison will be 6 in Nov and I'm petrified she'll get out when I'm asleep or something. I have chain locks on both of our doors not to keep out intruders cause those pitiful little locks wouldn't do much but to keep Allison in. When I see Tiffany or Mark later I'm going to suggest that they get some of these chain locks because all it would take was her falling in that pool. If we're asleep theres no way we'd find her in time. It scares me to think she was out there this morning. Our dogs are good natured they don't bite and they sort of know her. Dan, our sheltie, is getting old and cranky and that scares me too. He's 7 now and gets irritable sometimes. U don't think it would be rude to suggest the chain locks to them do u? I like them both. He's my age and she's 23 and Adam and I are thrilled to have them as neighbors. Haileys a sweetheart. I just don't want her hurt or worse, I'd never forgive myself. I still don't know why he was laughing. He come in and said he performed a rescue in the back yard. He's part of a paramedic first response thing at work and he's always stopping on the sides of the road when we see ppl pulled over to see if they need help. He takes it pretty seriously and he got serious when he thought about her falling in that pool. I think he was laughing cause something about the only reason she was crying is because she had her shirt twisted while she was swinging and couldn't untwist it. Oh well, I am going to suggest the chain locks for their doors or some sort of lock they can put up high and lock at night or when he leaves. I unchain ours every morning before Adam comes home so he can get in but other than that if we're asleep its locked.

i think you dont have to sound rude, you can just be concerned.  I am sure the thought has occurred to them as well
