what do ya think

So umm alot of ppl around me believe that "forever" does not exist and when i asked why they would never give me a proper answer like i do respect opinions but i just want to know why like i believe that forever does exist. For example, take love. When someone tells u they will love u forever and its actually genuine then yh they will forever. lmao some of u must be so confused ok so i think that forever has a time limit which is the span of our life so take an old couple and their promise was i will love u forever blablabala and the old lady died and the old man was able to love her until his death then i guess forever is fullfilled but IF there is a afterlife then MAYbe that forever goes on but yh i belive that everything has a timelimit
