Has anyone tried learning another launguage

I took French for a semester in 9th grade. Dropped that like 7th period French...ha, it WAS 7th Period French! Sitting in an 80 year old school room from 2:20 to 3:10 PM in September when the beach was a mile away? I took Spanish in community college for a year, bombed that too, pulled a C- and I think I still got 'credit' for it but barely. I hear linguistics is an aquired talent and some people got it , others dont. I can remember off beat things from a technical manual or procedures but for the life of me I could not put a sentence together let alone write one in Spanish or French. Im older now and can understand a little more spanish as I work with many spanish customers. Immersion is the key, use it or lose it. My Kids now taking French in high school and hes asking me how to pronounce things and SOB, a bunch of things just came back to me from some door in my brain that hasn't been opened in 38 years. I could listen to French radio for hours, Spanish radio, hell no. Vietnamese or Farsi? F no, I'd be running out with my hands over my ears! Best friend in 3-5 grade was a Vietnamese refugee spoke no English. His mom would talk to me for hours in Vietnamese like she thought I understood her.
