Four Things that make me nervous listed not in any particular order
1) Injection - The mere thought of taking a shot makes me dizzy
2) Balloon - A person blowing balloon in front of me where I cant put my hands over my ears. It makes me very nervous just waiting for it to burst any moment
3) Deepavali Pattas - A cracker whose fuse fire has been just lighted but which doesnt burst. The fuse wire just giving few sparks and dies and we still dont know if it is going to burst or its a goner.
4) Stray Dogs - The thought of driving past stray dogs which I know for sure is going to chase me.
