No you should be lucky those are the only "bad" social habits you have. If you think trailing off or mumbling is bad, try stuttering on every single word or laughing way too loud like someone who's actually socially awkward.
I loved it when I was on a swim team and we'd party like rock stars in the hotels and literally wipe out the joint of food xD And the pool would always be full even though we'd spent the entire day in the pool. Hotels are just awesome
Shoot your alarm clock to turn it off each morning. but wouldn't you have to grab the gun which takes the same time as turning the alarm clock off. and then you'd have to shoot the target when you're half asleep to turn the darn thing off.
