We were camping along the beach in Southern California, the MH behind had an older couple and I noticed he had a tool chest out and kept going in & out of the MH always looking perplexed. I went over and asked if they were having a problem. He said they had a leak and he couldn't fix it. I offered to help, it turned out to be the connection for the cold water on their bathroom sink. I fixed it.
They were staying for a couple of weeks and so were we. After a few days of spending time together, even going into town for lunch; their 10 year old Granddaughter came to stay with them for awhile. A couple of days went by and the couple needed to head in to town to dump. They asked if we would watch their Granddaughter while they went in to town. We did.
For years we kept in touch with them and would from time to time meet for a camping trip. They lived in Texas but would come to California every couple of years to stay by the beach.
