I hate to be late. I am forgiving to others who are late. That is unless their tardiness delays my being at a particular place at a particular time for a particular reason - such as attending a movie, meeting someone for dinner (ie being there on time for a reservation) or arriving at someone's house when there is a set time. (A caveat being when the invitation is for "some time around ...") The former situations or tardiness on my part, honestly, makes me anxious.
Personally I feel it is rude to make someone wait. In my opinion, even calling ahead to say one is late (although it advises the other party of the delay) is still an inconvenience for those who are waiting. We all have friends we know are habitually tardy. In those cases we often take that into consideration. "Well we will plan to eat at noon, but since we all know Harry is going to be 30 minutes late, it will be 12:30 at the earliest before lunch will be served."
I am an early riser, a morning person, and have been most of my life. I usually get up around 5:30 in the morning and by 8:30 in the evening, unless I have other plans, I am in bed reading. (In full disclosure I actually do not fall asleep until 9:30 or 10.)
As many of you know, I have 2 pups - Marshall , a full size Yorkie, and Ellie, a 'Norwhat' (A Norwich terrier, who thanks to DNA we learned is actually a Norwich/ Cairn mix). Honest to God, Ellie's little internal Mickey Mouse watch alarms around 5:25 every morning, usually before my alarm clock rings. If I am not already awake, she makes it very clear that I should be. With her consistent whining and/or standing next to my face staring at me, I am awake, whether I want to be or not. However at that time on these cold mornings ,when the temperatures are in the 30's at best, the idea of crawling out of bed to bundle up and go for our morning constitutional, is anything but inviting. Tell me who really enjoys walking their dogs when one can see their breath in the cold dark air and the frost on the ground is 'crunchy'.
On these mornings or those when I am not working, I am not given to enthusiastically jump out of bed and hurry outside. Often I find myself negotiating with Ellie. "We really do not need to get up this early, please go back to sleep." I will cover my face (to avoid the guilt her pleading visage evokes). I will offer enticements. "Just 30 minutes more and you'll get a treat if you go back to sleep." This may get me 15 additional minutes at best, but rarely much more. With her tough Scottish breeding, cold mornings are not an issue.
Perhaps our Harrys should have such a companion, with an internal watch and the persistence of a terrier, to keep them on time. Just saying.
