history: Once I met someone who told me they were related to Elvis. I believed him but now I am not so sure. My friends say I am too gullible. I met someone the other day who said they are the grandson of Elvis. I believed him but now I am not so sure. Well_comma_ he is probably lying.
current: You are probably right. My friends say I am too gullible sometimes.
next: Elvis only had a daugther, so the chances of him telling the true are slim
