I Am a Bad Liar

If i have to think about lying then I suck at it. But if I'm under some sort of stress or I'm in a hurry & need to get out of a situation then I'm pretty good liar. But overall not a good liar lol. I think my family thinks I'm a good liar But that's because i have shitty memory & recall things differently or just don't remember them. But luckily i was able to explain this to my mom & she finally gets it (probably because her memory has gone bad after surgery which is why she finally gets me)
