its a matter of choice, it has nothing to do with humbleness or modesty just lack of manners. i know many ppl who talk too much mostly talk without thinking. lots of times they say things that shouldn’t b said. they infact have shallow personalities. plus these ppl mostly say n pretend wat they r not. n yes by nature i’m not into unnecessary talking so that can be a reason too. it has nothing to do with being insecure. y should i be insecure of talkative ppl. i infact get bored by them
